I applied through university. The process took 2 weeks. I interviewed at DRW in Oct 2019
Interview
Met with DRW at a university career fair, applied online. I was given a 30 minute math assessment consisting of 4 questions, I did not do well and got a rejection e-mail a few days later. There was an optimization and matrix algebra problem that I ran out of time on, a probability problem that was not worded well, and a hyperspace problem I have no idea how you're supposed to solve if you don't just have 2 numbers memorized.
Interview questions [2]
Question 1
For an n-dimensional unit sphere, the volume and surface area peak at i and j values. What is j-i?
There is a weighted coin, P(heads) = 0.6. The coin is flipped 4 times, if it's heads A wins 1$ if it's tails B wins $1, what is the expected value of a bet where if A wins overall, you get his winnings, if B wins overall you get 0.
3 prob & stats questions - first round tech interviews. Interviewer is a trader. Questions are classic but need to be answered quickly so need some practice before the interview. I heard there will be 6-7 rounds overall
A very standard prcess. Firstly introduce myself based on the resume.
Some questions based on my previous experience are also expected.
The final step is a short brain teaser which is more like a routine with very low weight in the interview.
3 rounds zoom interview, first round with qr discussing about resume and some basic stats/linreg, second round with a pm with multiple math questions, and third round with the hm, talking about option pricing.
