I applied through college or university. The process took 2 weeks. I interviewed at DRW (New York, NY) in Dec 2021
Interview
There was an online assessment. I did not get past this so I cannot say more about the rest of the process. Questions were hard. It was especially hard to complete the questions on time.
Interview questions [1]
Question 1
Probability, Linear Algebra, Markov, Data Analysis
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.
