Aditya Vats, studying in IIT Kanpur as a BT student in ME will do
his summer internship in Techno-Managerial profile at ITC Limited. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
HUL

## Insights on the Selection Process
1. The first round is filling a very detailed form. This constitutes everyThing from your achievements to your life goals etc. I believe it’s to understand how actively you are engaged in progressing your career and yourself.

2. Second round is basically the short listing for GD. The short listing is done on the basis of your form, your CPI, and your resume. I believe a CPI > 8.5 will suffice.

3. My GD was online and it was a very quick case study. A situation was provided and 3-4 people were asked to come to a consensus for a solution. The selection over this was pretty much how any GD selection goes. You speak up, speak logically, don’t criticise, be courteous but put your point across. 

4. After getting selected, you have another 2 rounds of interviews. You must be very thorough with your resume. Technical questions were asked of me but not related to my coursework. Some general stuff like what motors do we use in our bot (related to a project of mine). So have at least 10 minutes of speaking content on each of your project points (yup, 10 minutes for each bullet point). Be very thorough here.

5. Almost all the questions were about your resume points. So if you had written for eg something about Random Forest Classifiers, they are going to go to the depth of it. So ensure that you are able to justify all your points.They may ask very unrelated questions, that they know you don’t have the technical expertise to know. These are just to ensure you don’t get baffled by stuff. Stay calm and answer to the best of your abilities.

##  Preparation Resources
I was not really preparing much for internship. I had done some GD practice with my friends, at least 3-4 mock GDs. Was doing some coding on interviewbit and some quant practice (50 challenging problems etc). I was not very rigorous in my prep. What helped me I guess, was that I had done lot of work in my semester time, Projects, Teams, Internship. All that actually helped me in the ITC shortlisting.

## Advice for students (dos and don’ts)? 
I would suggest to stay calm and relaxed in interviews. A relaxed and positive vibe actually creates a big difference in such interviews. Nobody wants a nervous wreck in their company. So smile, make light conversation with the interviewers while answering their questions seriously. That shows that you are confident in dealing with new situations.




Akshat Sharma, studying in IIT Kanpur as a BT student in CSE will do
his summer internship in Software Engineering profile at Graviton Research Capital LLP. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Quadeye (Software engineering intern), Optiver (Software engineering intern)

## Insights on the Selection Process
The Graviton interview involved 2 coding questions. The first used trees and recursion, the second was quite unique and based on discrete mathematics. No questions from dynamic programming/graphs were asked. 

The second round of the graviton interview involved a lot of questions from computer organisation (CS220). They asked questions based on memory management(about heap,stack, global pointer memory allocation), how the memory stack is maintained in programs(they gave an example program and asked me how the stack would be arranged), pipelining, hazards related to pipelining.

The last question was a practical one based on how cache misses and branch prediction influence performance and how to write code that keeps these points in mind. Most of the above points are covered in CS220 (other than the pratical aspects of writing code)

##  Preparation Resources
1.) For Coding practice : Interviewbit(website), Geeks for geeks(website). 

2.) For Algorithms theory : Introduction to algorithms by Cormen. 

3.) For Probability : CS203 course slides, Brainstellar(website).

## Advice for students (dos and don’ts)? 
Start preparing at the start of your summers. Try to identify which profiles are of your interest. Get your resume checked with atleast 5 seniors. If applying for high frequency trading profiles then knowledge of the market is a must. Try and be consistent. Be confident and formal during the interview.




Ananya Gupta, studying in IIT Kanpur as a BT student in CSE will do
her summer internship in Quant profile at Quadeye. Here are some brief
insights of hers.

## Shortlisted Profiles & Companies:
Goldman Sachs - Summer Analyst, Uber - Software, Graviton - software, Sprinklr - Software, Microsoft -Both software and data science 

## Insights on the Selection Process
I gave interviews for 3 companies out of the ones I was shortlisted for. 

1.) Goldman Sachs:- 
I had 2 rounds, some people had to appear for 3. Both were technical rounds. In my first round, I was asked 3 questions. One was based on basic probability, one was based on DFS in a matrix (just the algorithm, not coding) and last one was an analytical puzzle. In the second round, it started with a discussion on my second year summer intern, then I was asked differences between arrays and linked lists, where can doubly linked lists be used in real life, etc. Then, there was a question on indexing in a DBMS, 2-3 direct questions from 50CP/brainstellar. The second round was much longer than the first one. 

2.) Quadeye:-
Here, I had continuous 4-5 rounds without break, some were even 10 minute rounds. The questions were mostly based on probability and puzzles (not from brainstellar/50 CP, you need to think fast on the spot), 1-2 questions on describing the algorithm for a particular problem and even some on mental math (like 105 square, 39*41, etc).

3.) Uber:-
I gave one round only, since Quadeye made an on the spot offer. I had to code two questions, they were pretty straightforward. One was based on prefix sum and hashmaps and other was based on DFS on a binary tree.

##  Preparation Resources
1.) For coding practice - Interview Bit and LeetCode

2.) For probability and puzzles - 50 CP, Brainstellar and IB puzzles

3.) For statistics - YouTube videos on hypothesis testing, regression 

4.) For OOPS theory - Tutorialspoint, Gfg

## Advice for students (dos and don’ts)? 
For tests:- The hard part is getting shortlisted for interviews. Try to do regular coding practice over the summers if you're aiming for SDE profiles. I didn't do codeforces, codechef, etc, I focused on IB/LC only. For quant companies, few of them don't take tests and CPI plays an important role there. Like for GS, a high CPI will give you a better shortlisting chance even if you mess up your test. APT portfolio, alphagrep, GS, etc will have a section of questions on probability and statistics, JEE type math. Having practiced timed tests will definitely help you out here. For data science roles, brush up your ML knowledge. MS data science test had 2 questions in which we had to code models (regression using sklearn, etc) and also a section on theoretical MCQs. 

Revise all concepts of DSA, have a good theoretical grasp. Do not skip over graphs part while practicing coding. Be thorough with OOPS concepts too. Do not forget to do brainstellar and 50 CP if you're aiming for quant profiles (can be done in 2-3 days). In your summers, trying doing one project/intern in the area you're interested in along with intern prep. 
For interviews, try doing 1-2 mock interviews before you give the real ones, it'll help you adjust to interview setting. 

Lastly, keep in touch with seniors, ask them about the companies you're aiming for and their procedure. Take tips from them. It'll help you guide your preparation in the right direction.

her summer internship in Product Engineer profile at Sprinklr. Here are some brief
insights of hers.

## Shortlisted Profiles & Companies:
Google India - Software Engineer, Goldman Sachs - Summer Analyst, Optiver - Software Engineer Internship, Uber - Software Engineer, Sprinklr - Product Engineer

## Insights on the Selection Process
In Goldman Sachs, there were questions related to probability and stats, puzzles 
In Google, Uber, Sprinklr only coding questions were asked in all the rounds
In Optiver, questions related to CS fundamentals are also asked apart from quant and coding questions.

Other insights on the interview process - 
1. Think out loud. Interviewer wants to see your approach so you should keep explaining your thought process.
2. Communicate well (very important to ace an interview).
3. Try to catch the hints that the interviewers give. Usually when you are going in the wrong direction or taking a long time to reach to the solution, interviewers give you hints.
4. If you think you are taking a lot of time, then ask the interviewer to guide you.
5. Try to think of corner cases and build upon any cases that the interviewers tell.
6. Practice the standard questions that can be asked related to any topic well.
7. Lastly, do not panic. Keep calm and keep smiling :)

##  Preparation Resources
[Leetcode](https://leetcode.com/), 
[Brainstellar](https://brainstellar.com/), 
[Interviewbit](https://www.interviewbit.com/), 
[50 challenging Problems in Prob and Stats](https://drive.google.com/file/d/14JZmX7DsGnwLLdlOVYqLL0u5re60SJWl/view?usp=sharing)

## Advice for students (dos and don’ts)? 
1. Start your preparation as early as you can. 
2. If possible, do group studies and discuss your approach to a question.
3. Talk to a lot of seniors about the internship preparation and keep in contact with them.

Ankit Yadav, studying in IIT Kanpur as a BT student in ME will do
his summer internship in Software Developer profile at D.E Shaw India Pvt Ltd. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
NA

## Insights on the Selection Process
Questions Related to Dynamic Programming, Graphs and Binary search and very basic questions regarding OOPS were asked.

##  Preparation Resources
1. Interview Bit ( Programming and Puzzles)
2. Codeforces( for pclub contests only)
3. CSES Problem Set (to consolidate a topic if enough time is there)
4. Competitive Programming - 3  (BOOK by Steven Halim and Felix Halim)
5. Brainsteller
6. GeeksforGeeks

## Advice for students (dos and don’ts)? 
Most important thing is to have good peer group for discussing questions, find people with common interest, keep giving contests organized by pclub and you must keep learning things which you don't know and due to which you were not able to solve a particular question in company tests and contests. My personal advice would be to First do each and every question from Interview Bit and keep learning things you don't know from geeks for geeks, for graphs and Binary search read theory (no need to do questions if you don't have much time) from the book I mentioned(CP-3 by Halim). For DP do every question from Interview Bit and also do some questions from CSES problem set for building confidence, for quant profile do Brainsteller and interview bit Puzzles, if you get stuck refer to GeeksforGeeks for that question and YouTube if still not clear.




Antreev Singh Brar, studying in IIT Kanpur as a BT student in CSE will do
his summer internship in Quant Researcher profile at Tower Research Capital. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
N/A

## Insights on the Selection Process
1. Resume Shortlist: Based on CPI
2. Test: Technical test was taken - OS / Network and CP based questions
3. Interview Process: 2 Rounds of Technical and One small HR round. Both technical rounds revolved around probability , statistics , data structures and puzzles. The HR round was more of like a brainstorming session on dealing with a open ended finance problem. Just like an informal discussion.

The Resume selection criteria for all HFTs is just CPI along with your branch. Its simple as that. So if you are in CSE with 9.5+ , you should get in most HFTs interviews. Tower had a technical test, so you had to perform well in it be shortlisted. Interview rounds were hard, the data structure questions asked could be weighted at about 1900-2000 on codeforces. The probability ones were straight out of CS203 course and 50 interesting problems in statistics book. The informal HR round was fun.

Interview Questions: You have 2 sticks with an error of ‘a%’ and ‘b%’ (while measuring length). What is the minimum percentage in error you can get while measuring the length of the stick formed after joining the two sticks.

##  Preparation Resources
Data structures : Codeforces , Interviewbit

## Advice for students (dos and don’ts)? 
1) Code and improve CPI
2) Don't lose your cool




Arpit Maheshwari, studying in IIT Kanpur as a BT student in EE will do
his summer internship in Associate profile at SAMSUNG Electronics South Korea. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Graviton (Quant), Microsoft (SDE), DE Shaw (SDE)

## Insights on the Selection Process
People from CSE and EE branches were allowed to give the coding test

Coding test-
1. There was 1 coding test of 3 hours duration. The test consisted of 1 question.
2. The test was not too difficult. The time complexity bounds were also not too tight for the given constraints of the question which essentially meant that brute force solution also worked. Still, it was lengthy and one had to be careful with the edge cases. Apart from the number of test cases passed, the time taken to solve the problem was also a factor which was considered.

Interview-
1. It consisted of 2 rounds - HR and Technical
2. A coding question was asked in the technical round. It was based DP. The problem asked in the interview was based on Knapsack
3. The HR round had general questions like "Why do you want to work for Samsung?"," Do you know anything about Korean culture?", and things based on similar lines.

CGPA plays a crucial role in getting shortlisted. 14 people were shortlisted for the interview, out of which 6 were finally selected. Among those 6 people, 5 were from CSE and 1 from EE. These numbers generally remain similar every year.

##  Preparation Resources
1. For Coding- Interviewbit, leetcode, contests on Codeforces for time-bound practice. 
2. For Quant- Brainstellar, 50 challenging problems

## Advice for students (dos and don’ts)? 
1. I would say that first chalk out a plan for yourself because every person is in a
different scenario with varied strengths/ weaknesses, so try and figure out what
works best for you.
2. Start early so that you have enough time to figure out things and prepare accordingly
3. Talk to seniors. This is very important since they are the people who have gone
through similar situations and can easily guide you throughout the process.
4. Finally, don't get bogged down by any hiccups that you may face. Stay focused
and don't let your self-confidence go down. It is easier said than done but then it is
the reality and it matters a lot.




Atur Gupta, studying in IIT Kanpur as a BT student in CSE will do
his summer internship in Quant profile at Quadeye. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Optiver - Quant, Tower Research - Quant, Alphagrep - Quant, Alphagrep - Software, DE Shaw - Software, Sprinklr - Software, Goldman Sachs - Analyst, Microsoft - Software

## Insights on the Selection Process
In all of the quant interviews (Alphagrep, Quadeye, Goldman Sachs) except Tower and Optiver, I was asked questions straight from the website Brainstellar and 50 challenging Problems book. In Tower, I was asked questions on standard deviation and variance on random variables, which was something I neither expected nor had prepared for. For optiver, you have to be really good at mental math and the concept of expectation in probability. 

##  Preparation Resources
1.) For Quant -  Brainstellar and 50 Challenging Problems 

2.) For Software -  Interviewbit mostly. Preferred solutions given in discussion section of leetcode for the same questions. 

## Advice for students (dos and don’ts)? 
1.) If you're a student reading this before the summers, my first and most important advice would be for you to focus on increasing your cpi as much as you can. It is extremely important to get shortlisted in good companies. Definitely keep it above 9 if you're targeting Day 1 companies.
 
2.) As for software profiles, Competitive programming is a must for companies Google and Rubrik, and maybe Uber too. For other companies like sprinklr, microsoft, etc just interviewbit would be fine.  

3.) Now for Quant profiles, both brainstellar and 50 challenging problems, are necessary and sufficient. Do both of 'em twice at least. I was also asked mental math problems in some companies' interviews (Quadeye, Optiver). 

4.)Some general tips -  The projects and internships on your resume don't help much (at all?) in getting shortlisted for interviews. It's just CPI and tests. As for interviews, what's required is that you should be able to explain why you'd be a good fit for the company and the relevant role. For this, the relevant projects/internships can help.

Chaitanya Sahni, studying in IIT Kanpur as a BT student in ME will do
his summer internship in Techno-Managerial profile at ITC Limited. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Hindustan Unilever (Techno Managerial)

## Insights on the Selection Process
1. Resume Shortlist and personal questionnaire form : High CPI is important
2. GD: Directed GD amd GD usually presents a moral dilemma as topic where you choose what to give priority to.
3. Interview Process: There were 2 interviews in total post GD. The first interview was more on the technical side whereas the second was a general interview seeking to know more about your personality.

The personal questions form should be filled with care. The answers should show clarity in the direction you are headed. For the GD the best steps to follow are to be aware of others peoples points and not repeat. Also you should try to bring a different angle from others. Stick to your decisions and make arguments in a formal manner.

The GD question for me was related to a company which gave workers houses within the company plant. The house allocation was usually done on seniority basis however we were presented with a dilemma in this case were there were some special cases in addition to the senior most worker. We were to decide based on this who we would allocate the house to. The technical interview was focused primarily on my resume. They asked in depth about projects I was pursuing and some course related questions as well.

##  Preparation Resources
My preparation for the GD was done by interacting with some seniors and taking part in mock GD’s arranged by the ANC. After the GD I did some basic research into standard interview questions and prepared myself for those. Apart from this I also did some background research on the company I was interviewing for. We must be prepared for what we have written in our resume as they will surely pick up on those points and ask to explain them.

## Advice for students (dos and don’ts)? 
Be thorough while preparing resume. Do not panic or feel dejected when you do not see your name in the list. Intern season is stressful, prepare well beforehand and dedicate time daily for your betterment. Apart from this focus on your soft skills as they also play an important role to get you intern.

Dipanshu Garg, studying in IIT Kanpur as a BT student in CSE will do
his summer internship in Systems profile at Quadeye. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Graviton, Alphagrep, DE Shaw, Rubrik, Google, Sprinkler, GS

## Insights on the Selection Process
Topics - Data Structures and Algorithms, OOP, Probability

Company specific shortlisting:

1.) HFTs software - (Highly) biased towards high CPI. Some don't even conduct tests. Tests are of moderate difficulty.

2.) Rubrik - Shortlisting purely based on coding test. Quality of questions is really good. You should be comfortable with solving A/B/C/D problems in a CF Div 2 round.

3.) Google - Resume shortlisting + test. Do participate in Kickstart/Codejam. If you secure good ranks in them, mention them on your resume as it is a big plus.

Interviews:

1.) HFTs software - Besides DSA, they might expect some knowlege of OOP preferably in C++.

2.) Rubrik - Similar to test just in a different format.

3.) Google - Tricky DSA problems. Also you need to code in a google doc.

##  Preparation Resources
Codeforces, InterviewBit, Leetcode, Fifty challenging problems in Probability

## Advice for students (dos and don’ts)? 
Try to maintain a good CPI. Also start preparation early.




Gaurav Manwani, studying in IIT Kanpur as a BS student in Mathematics will do
his summer internship in Quant Trader profile at Optiver. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Optiver (Quant Trader), Jane Street(Quant), Optiver(Software), Sprinklr(Software) and APT Portfolio

## Insights on the Selection Process
Knowledge of various puzzles came in handy. Software interviews had questions on advanced DS (heaps and trees), computer fundamentals and cryptography applications (since it was mentioned in my resume). Some parts also connected to networking and systems design, although these topics weren't mandatory to cover.Quant interviews involved a lot of probability puzzles and games based on expected value (with added time constraints from the interviewers just to check how you react under pressure)

##  Preparation Resources
InterviewBit for DSA practice, 50 challenging problems for quant prep

## Advice for students (dos and don’ts)? 
The first and foremost advice would be to be patient, and wait for the right opportunities rather than jumping blindly into everything. Build a strong academic background related to the profiles you're targeting. Try to be technically adept in DSA (and/or quant topics) by the time of tests.
However, confidence is key for the interviews. Express your ideas freely and try to catch hints from the interviewer (trust me, they give a lot of subtle hints). Appropriate technical preparation always gives you a boost, but practice handling situations where you don't have any technical knowledge to answer the question. Reacting well to a pressure situation even when you're clueless about the question/subject is the most important interview skill in my opinion.
Be patient, prepare well, and let your heart out! Best of luck!




Gurbaaz Singh Nandra, studying in IIT Kanpur as a BT student in CSE will do
his summer internship in Systems profile at Quadeye. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Jane Street, Optiver, Quadeye, Sprinklr, Microsoft, Goldman Sachs

## Insights on the Selection Process
1. Resume Shortlist: Branch CSE and CPI > 9 was the criteria

2. Interview Process

a. Interview rounds = 1

b. Duration = 1 hour

c. Type of question asked during interviews: There were a
total of 4 interviewers, roughly interviewing for 15-20 min
each:-

        i. Basic introduction, general questions related to C/C++, STL implementations e.g. set vs unordered set, pass by value vs pass by reference etc.

        ii. DSA questions on linked list.

        iii. DSA questions covering DP, Stack, and Sorting.

        iv. Puzzle round.

d. No quant related question was asked as such since they
already asked the preference at the start of the interview.

e. In general, the questions were basic to medium and one
could answer confidently given he/she has done a
decent prep.

##  Preparation Resources
Interview Bit, LeetCode, GFG, Fifty Challenging Problems in Probability, Gurmeet Puzzles and Brainstellar

## Advice for students (dos and don’ts)? 
Do:

● Sitting for non-core/software roles, coding preparation, without any doubt, is a must.
Utilize the summers well and be consistent in solving questions on coding platforms.

● Put a bit of work daily on improving your communication skills. There is no fun if you
know the solution to an XYZ technical/HR question but fail to communicate it
effortlessly to the interviewer.

● Start working on building your resume and reviewing it from seniors early. Else it
unnecessary creates last-minute panic.

Don’t:

● Waste time in comparing yourself to others and looking down upon yourself. Rather
focus on your own growth and efforts.

● Pull other legs down or demotivate others. Intern/placement times could be
overwhelming to one’s physical and mental health, and you should rather be
supporting and motivating others than making fun of their misery.




Gyanendra Kumar, studying in IIT Kanpur as a BT student in ME will do
his summer internship in SWE profile at Microsoft. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
N/A

## Insights on the Selection Process
I have only 1 round of interviews with Microsoft as I was a part of Engage Mentorship program. The round is named AA round (As Appropriate). There is only one interviewer, and he has an experience of more than 20 years with Microsoft. Since I was a part of the mentorship program, the initial 15 mins discussion was on my project. He asked me to give a quick demo of my project, open the source code, and explain what I have done and why I did it. Then he asked about my previous internship experience, which was very brief (2-5 min only). After all this, they came to DSA ( Data Structure and Algorithm). He put one sample test case of the linked list in the comment box and asked me to predict the possible question. I predicted around 4-5 possible questions. Then he gave me a second test case, and I was successfully able to predict the questions. The question is straightforward once you predict the question. The question is as follows: Given a linked list, split it into two halves, reverse both halves, and connect the end of the first linked list. In the end, they ask me to code the same problem.

Rishabh Dugaye, studying in IIT Kanpur as a BT student in CSE will do
his summer internship in Product Engineer profile at Sprinklr. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Uber-SDE, Microsoft-ML

## Insights on the Selection Process
For Sprinklr:

1st round had Questions on Binary search, Median of stream of numbers,Implementation of heap and basic questions about sorting algorithms.

2nd round had questions on base conversion,Least recently used cache using DLL and SLL,Implementation of Trie and one puzzle which was from brainstellar hard.
In both rounds I was also asked about my projects and internships.

3rd round was HR.

For Uber:

1st round had a easy question on BST where given a BST root and a target T we need to split the tree into two trees where 1st tree has all nodes with values less than V and 2nd tree had value greater than V.This can be solved easily using recursion.

2nd round was HR and discussion on project.

3rd round was coding and had a problem implementation problem in which I was only supposed to write pseudocode of a brute force solution.

##  Preparation Resources
Coding-Interview Bit and PClub Archives.

Quant-50 challenging problems and brainstellar.

## Advice for students (dos and don’ts)? 
I would suggest to start coding from May. In my opinion interview bit is sufficient for most of the companies. If you are preparing for companies like google, rubrik, TRC then you should really focus on doing competitive programming on codeforces. Apart from that P Club archives are really helpful and gives you a really good about about the difficulty of tests.




Saksham Mehra, studying in IIT Kanpur as a BTech student in EE will do his summer internship in Hardware Engineer profile at Google. Here are some brief insights of his.

## Shortlisted Profiles & Companies:
NA

## Insights on the Selection Process
Google shortlists students directly on the basis of resume, without any tests. Having core EE projects on resume is the key.  There were 2 rounds of interview. First was based entirely on verilog . Second round was more focused upon the digital part of ESC201 and there was one coding question .If you are thorough with your concepts from EE courses, you can crack the interview . Some questions are tricky , but the interviewer keeps on giving hints at points where you get stuck. The questions are focused upon the real life application of your EE concepts.

##  Preparation Resources
1) Most important is 2nd year core EE courses like EE210, EE200, EE250 and ESC201. Going through the lecture material , giving to you in these courses should be sufficient. 

2) You can also go through the CMOS inverters part of the EE370 lectures as a plus, if you are thorough with ESC201 and EE210. The EE370 lectures are available on YouTube.

3) Having a decent knowledge of HDL, such as verilog/VHDL(any one) is also important for the interview process. I prepared for it from CS220 lectures (available on course website). However any online tutorial may suffice. The above resources are general for all core EE profiles.

4) For software roles, I mainly focused upon solving questions from Interviewbit regularly and also revised ESO207 concepts.

## Advice for students (dos and don’ts)? 
1) Luck factor plays a major role in the internship process. So do not worry if you are not able to get shortlisted or crack the interviews. Keep patience and believe in your skills , whatever profile you are preparing for. 

2) Also refrain from applying for every profile. Make sure, you decide by the start of the summers , which roles you are preparing for, and focus your time and energy on them. 

In case of any other doubt , feel free to contact :)

Shorya Kumar, studying in IIT Kanpur as a BT student in EE will do
his summer internship in Product Engineer profile at Sprinklr. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Optiver, DE Shaw, Graviton (SDE and Quant)

## Insights on the Selection Process
Quant 
1. Puzzles on probability and expected values 
2. Strategy and game theory puzzles 

SDE 
1. Data structures and algorithms 
2. OOPs and Resume 
3. System design interview (for Optiver, which was a complete surprise for me but you better be prepared)


##  Preparation Resources
Codeforces, Atcoder, GFG, Leetcode, Brainstellar, 50 challenging problems, A guide to Quantitative finance 

## Advice for students (dos and don’ts)? 
1. Try to be patient and sit tight, you will see people getting shortlisted and your name not in the list even when you expect it to be, don't loose hope.
2. Don't write SQL in your resume if you don't know it inside out. What I mean is if you are mentioning use of any technology in your resume then expect questions on it.
3. Look at what the company does before the interview and make sure to ask questions to the interviewer after the interview about his experiences, work life, what you will be working on, etc.




Shubh Agrawal, studying in IIT Kanpur as a BT student in CSE will do
his summer internship in Software Development profile at Rubrik. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Google, Rubrik, Uber, Graviton, Tower Research, Quadeye, Microsoft, Sprinklr

## Insights on the Selection Process
In SDE role, most of the interviews are based upon algorithms and Data Structures only. You will be given questions and you will have to solve them and write code/pseudo code and then even explain it. Explaining is the most important step. Also try to give good names to variables, in one of the interview I was asked to change all the variable names so that the code looks good. Also in some cases you might be asked questions from some of the courses, but that chance of asking that is less.

In quant roles, generally  puzzles and probability questions are asked. 

##  Preparation Resources
Interviewbit, CodeForces

## Advice for students (dos and don’ts)? 
Try to wrap up all the things you do in summers by June end. From July the things get a bit time consuming, you will first have to give time to make resume and then the coding rounds are soon lined up and then preparing for interview. All this require much time.
Also do practice from the test series from archives, they are really good set of question.



Shubham Sanjay Korde, studying in IIT Kanpur as a BT student in EE will do
his summer internship in Techno-Managerial profile at ITC Limited. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Hindustan Unilever (Techno Managerial)

## Insights on the Selection Process
Shortlist
- Shortlisting done on the basis of Resume + Application form
- A good CGPA helps
- Having a project and a POR beneficial 

GD 
- Group Discussion with a batch of 6 people
- Common problem statement is given. You have to choose an option and try to convince others why that options should be choosen.
- Sample Question: There are 5 people who want to get an apartment in the residential complex. The traits and characteristics of all the 5 were given. Like one of them was the senior most, one did crucial time sensitive jobs, one was handicapped and so on. We had to decide and explain whom to give the room and convince everyone else why that was the correct choice.

Interviews
- 2 rounds of interviews: 1 Technical and 1 HR
- Explain one of the projects on your resume.
- What are the two important internationally important topics you deeply feel about? (HR)
- Which will be your ideal company to join apart from ITC? (HR)
- All other questions were resume specific (most of it was  conversations)


General Insights
- Having a good CGPA makes selection way easier.
- Clear speech, logical structure in arguments and persuasiveness in manner beneficial in clearing the GD. Exposure to public speaking and GD practices will surely help. 
- Basic questions on core courses like EE330, ESO203, ESC201 can be asked. Although I was asked none. Same for Mechanical and Chemical core courses.
- Have basic info for HR round like CEO name, products of the company, primary business market etc.

##  Preparation Resources
- I did not specifically prepare for techno managerial profiles. I had been debating for a couple of years by then so it was relatively easier for me to crack the GD.
- I watched a couple of youtube videos on basic tips to perform well GD before the GD.
- Do not forget to ask your friends who have already been in one of the previous batches what the question was. I knew the question well in advance before the GD. Although the question was not super difficult, it could make a difference if you get more time to think about your answer.
- I watched youtube videos on HR interview questions and correct answers to them. None of them helped as HR interviews are basically conversations. 


## Advice for students (dos and don’ts)? 
- Have backup options ready if your target is techno-managerial profile because the number of good companies in this profile are very few. It is also possible because preparing for this profile does not require much hardwork.
- If you have never done any kind of public speaking or any such activity, practicing GD with your friends can be really helpful.
- Be as frank as you could during the interview. No need to fake. Most times the people interviewing you are extremely pleasant and make you feel comfortable. Take the interview just like a conversation. You wont even know when did the interview end.
- Don’t worry if you don’t get it. A significant part of the process is luck.




Soham Ghosal, studying in IIT Kanpur as a Double Major student in ME will do his summer internship in Software Developer profile at Google. Here are some brief insights of his.

## Shortlisted Profiles & Companies:
Rubrik (Software), Sprinklr, Goldman Sachs, Quadeye(Systems), DE Shaw

## Insights on the Selection Process
Google: Google interview had some pretty original looking CP problems. So if someone is well versed with cp, it's a positive. I was asked a question on binary search in the first round (and certain interesting followups, which eventually led to a recursive solution). Just ensure that you know the behind-the-scenes implementation of whatever data structure you are using. In the second interview, I was asked a segment tree question. The second round was considerably harder than the first one.

DE Shaw: DE shaw focuses a lot on the cs fundamental concepts. Be well versed with oops, os(if possible).

Rubrik: Rubrik tries to ask interesting questions in the interview. The questions were drawn from concepts in operating systems. It was an interesting interview for me personally.

Goldman Sachs: GS asked basic DSA questions.Leetcode should be enough for this. 

##  Preparation Resources
Codeforces, Leetcode, Atcoder, 50 Challenging Problems in Probabiltiy, Brainstellar

## Advice for students (dos and don’ts)? 
Do competitive programming. It might not seem relevant initially, but trust me once the tests start, it will work wonders. Also, CP enables your mind to always have a systematic approach, which is very much required in the interview. The interviewer is not there to just watch you code something up. While practicing, make it a habit to speak out your thought process. In the interview, make sure that you are able to convey everything you have in your mind to the interviewer. Finally, just be calm and remember that the interviewer is more of your colleague during the interview, and he/she will always be there to help you, in case you get stuck. All the best!"




Somya Lohani, studying in IIT Kanpur as a BT student in CSE will do
her summer internship in Software Engineer  profile at Uber. Here are some brief
insights of hers.

## Shortlisted Profiles & Companies:
Microsoft Machine Learning Intern, Google Software Engineer, Microsoft Software Engineer, Sprinklr Software Engineer 

## Insights on the Selection Process
For Microsoft ML, I was extensively quizzed about my past projects which were mostly reinforcement learning based. I was also asked questions on the probability concepts relevant to machine learning and different classification and regression models and where and why those models were relevant. All the software roles that I interviewed for, required me to have a good command on competitive programming and DSA concepts. I had to code the  solutions to the problems in real time. Questions based on OOPS were also frequently asked. For most parts, the companies (Software roles) I interviewed for did not discuss my resume at length. 

##  Preparation Resources
Interviewbit, Leetcode Medium level problems, CSES problem set, GFG for topic wise revision of DSA concepts and Machine learning Course by Andrew Ng.  

## Advice for students (dos and don’ts)? 
The process can be very stressful since luck plays a decent amount of role while getting you through interview shortlists and interviews. The key is to have faith in yourself and surround yourself with a good set of friends who are just as motivated and have your best interests in mind. There is no one model that works for everyone, so spend time figuring out what works for you and follow it religiously. 




Suhas S, studying in IIT Kanpur as a BTech student in Computer Science and Engineering will do
his summer internship in Quant Trader profile at Optiver. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
Optiver, Samsung Korea, Google, Rubrik, Goldman Sachs, Quadeye, Graviton

## Insights on the Selection Process
Samsung Korea: Unbounded knapsack. SK's technical interview usually contains a well-known problem. Make sure you explain it slowly. SK's shortlisting criteria changes each year so don't read between the lines too much. SK's HR round is the most important. Try and watch a KDrama before. 

Optiver: You can't really prepare for Optiver's interviews. Best thing I can suggest is to understand market making well and to play estimation and market making games before with your friends.

Google : Number of overlapping intervals, Dyanamic Programming

Rubrik: Subtree DP, Greedy that required a non-intuitive observation

Quadeye: Estimation, PNC Expected value, and some useful limits and approximations in probability, Zero sum problem 


##  Preparation Resources
50 Challenging problems, Brainstellar, Interview Bit, Cracking the coding interview, Codeforces

## Advice for students (dos and don’ts)? 
1) Best advice for coding would be to familiarise yourself with all the standard problems in different paradigms. Interview Bit does a good job at this. Then you can try LC medium or hard (depending on your comfort level). Also give archives seriously. It'll give you a rough idea of where you stand and also improve your temperament for giving timed tests. (refrain from using google during the contest). And it's also extremely important to be able to solve questions really quickly. On average you might get 20-30 mins per question, and you need to be able to write error free code within that time frame.

2) For quant, just try and solve puzzles from the above mentioned sources and try and remember it (maybe note down interesting problems and the trick to solve it). There have been instances where I wasn't able to solve a question I had seen before in the pressure of an interview setting.

3) Apart from all these technical things, the most important thing is to stay motivated and try and learn as much as you can during your preparation. I'm sure all of you are extremely smart and talented and can achieve anything you put your mind to. So believe in yourself!

Varun Gupta, studying in IIT Kanpur as a DoubleMajor student in CHE will do
his summer internship in Quantitative Researcher profile at AlphaGrep Securities. Here are some brief
insights of his.

## Shortlisted Profiles & Companies:
AlphaGrep - Software, DE Shaw, Microsoft, Goldman Sachs, Uber, Google, Optiver

## Insights on the Selection Process
Resume Shortlist: 8.5+ CPI

Test
- Both programming and aptitude questions

Interview Process
- 3 (In my case), can vary
- Logical Questions where one had to brainstorm the
entire process.

Perform well in the test is one of the key factors in order to get
selected.

##  Preparation Resources
To prepare for internship season, there are two major areas which one needs to practice, CP and Quant.

For CP -
1. Basic - if you are new to coding then first pick up a coding language (preferably C++, read about STL), understand different Data Structures and learn basic algorithms for graphs since
it is one of the favorite topics and build upon it.
2. Advanced – There are different websites where you can practice questions from. I recommend solving Interview Bit since it has many relevant questions. Apart from this I personally used Leetcode during the initial part of preparation and CodeForces towards the end. CP algorithms is a nice resource to widen your coding toolbox.

For Quant –
1. Revision Mso/hso
2. 50 challenging Questions
3. Brain stellar
4. Xinfeng Chau

## Advice for students (dos and don’ts)? 
If you fear giving interviews, then make sure you attend the mock interviews organized by both SPO and AnC Council. It is better to form a peer group while solving CP questions daily since there will be someone with whom you can discuss different approaches to solve the same problem. Always remember that interview is not just how much you know, but how much you can reproduce in a pressure situation. Maintain your nerves during the interview. While discussing the problem statement make sure you understand it perfectly, you need to ask the interviewer about the end cases. Think aloud during the interview so that interviewer can get to know the approach you are using. Start making resume at least a month before the submission and get it reviewed by some seniors.
