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

## 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)

## Resources that can be used for Internship Preparation

## Advice for students sitting in internship drive (do's and dont's) 
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!




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

## 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 


## Resources that can be used for Internship Preparation
50 Challenging problems, Brainstellar, Interview Bit, Cracking the coding interview, Codeforces

## Advice for students sitting in internship drive (do's and dont's) 
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!
