Overall was alright. First off had an online assessment consisting of 5 questions. After completing it was contacted a few days later for a phone interview. Interviewer was nice and we chatted afterwards pretty casually. He was also quite patient with regards to the technical questions.

    I applied through college or university. The process took 2 weeks. I interviewed at DRW in October 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.

    I applied through college or university. I interviewed at DRW in September 2019.

    They sent the online assessment. That was the hardest online assessment I ever had. There were 13 questions for 60 minutes. Also, they had a pseudo code as well. Lots of probability questions. If you read a book like interview problems for quant positions you should be fine.

    Interview

    By phone, just review CV and ask about my intern and project, no tech questions. I guess they may feel that I just learn programming for 1 year and not qualified.
    I guess no hope.
