Round 1 - One-on-one

  • Q2. Basic probability questions to calculate

Interview Preparation Tips

Round: Resume Shortlist
Experience: Students were shortlisted based on resume. Around twenty students were selected.

Round: Other Interview
Experience: Selected students for the first round of interview in which they asked puzzles/probability questions and tough HR questions.

Round: HR Interview
Experience: Four students were selected for the final round of interview out of which three landed the job. Final round was a very general HR round.

General Tips: No preparation is required but you could solve some common puzzles. It was very relaxed and the interviewers were very supportive. The main challenge was giving convincing answers to the HR questions.It's the best management job on campus!! Give your best! I'll be glad to help if any of you have queries.
Skill Tips: Make a very professional resume. Also for the interview, they do not expect you to know any finance so please do not claim to know finance and fumble when they question you (some guys were not selected because of this). I was upfront and told them that I lack any sort of knowledge in finance so I was asked only a few puzzles and some challenging HR questions.

Interview Questionnaire 

1 Question

  • Q1. Probability and Logical puzzles

Interview Preparation Tips

Round: Resume Shortlist
Experience: The company shortlisted based on resume and GPA. Around 20 were shortlisted.

Round: Technical Interview
Experience: After that they held a technical round wherein they asked mainly probability and logical puzzles. Theinterview was 10 to 15 mins long.

Round: HR Interview
Experience: The next round, for which five or so were shortlisted, was one in which they asked about your drive, your good and your bad, why finance, why this job, and other such questions. All the interviewers were present and this lasted for 15 minutes. Finally only 3 were given the offer.

General Tips: Look formal and energetic. Look them in the eye while answering, be courteous and practice thinking loudly. Think about what you would say when they ask you why you want to move to finance, and whythey should take you and not the others. It is not a tough one to crack. All you need is to be confident, polite and frank.
Skill Tips: Prepare your resume tailored to the company. Study up probability and tricky questions on it. They asked me a question on Russian roulette. Prepare for puzzles online.

Interview Preparation Tips

Round: Test
Experience: Though technical questions were not that difficult but the quant section was way too hard and almost impossible to solve completely in given time limit.
Tips: It’s better if you attempt less questions (in quant) but do them right (I attempted less than 40% quant and still got through).

Round: Technical Interview
Experience: Next they would have 2-3 technical rounds where they cover most of the areas of CS. Some of the areas where they concentrated more would be Algorithms, OOPS Concepts and Logical Puzzles.
Tips: Brush up important concepts from various areas such as Operating System, OOPS, Software Engineering. Be ready for some really challenging questions in Algorithms. Also they do ask quite a few logical puzzles so it’s important you practice a lot of them online before the interview.

General Tips: D E Shaw selects very few candidates + comes in starting weeks of placement season, so competition is immense. Multiple companies come on same day, so it becomes a little tedious. Surely I wasn't the better candidate that day.
Skill Tips: D E Shaw focuses more on your ability to solve logical problems, so make sure you are in best state of your mind and speak while solving any problem because what they are looking for is not the right answer (well of course they are) but also how are you approaching the problem.
Skills: Operating System, OOPS, Algorithms, CS, logical puzzles, Quant
