    Application

    I applied online. The process took 4 weeks. I interviewed at Jane Street (New York, NY) in October 2017.

    Interview

    Applied online and was emailed a day after. There are five (?) rounds in total I believe. They are pretty clear about the interview process (the person I spoke with explained everything in the beginning of the first round interview). The first two rounds consisted of mostly probability questions. I think most of the questions were expected value and didn't require a very deep understanding of probability (just have a solid grasp of the basics). Made it to the third round but that hasn't happened yet..

    Interview Questions

    • If I flip four coins and give you a dollar for every head, what is the expected value of this game?   1 Answer

    Application

    I applied online. I interviewed at Jane Street.

    Interview

    Four rounds, three on the phone one in person, got to the second round, all tech questions. Everything is probability or game theory, nothing that requires serious previous knowledge but must have strong intuitions for these and be able to explain thought process well.

    I applied online. I interviewed at Jane Street (New York, NY) in August 2017.

    Interview

    Lot of probability questions and quantitative concept checks. Got to second round phone screen, but messed up on questions that were not too diff. Would recommend this company, make sure to have a decent handle on probability and expectation beforehand though

    Interview

    Phone Interview. Overall the people were very pleasant/polite throughout the process, although you can tell the culture is extremely nerdy (not a bad thing) and that there is a strong emphasis on second order knowledge / non-overconfidence.

    • Time for hands on clock, basic binomial probabilities, sum digits from 1 -> 1M   1 Answer

    I applied online. The process took 2 weeks. I interviewed at Jane Street.

    Interview

    Phone interviews with math questions. First interview was pretty easy and they invited me to a second interview. The second interviewer never called at the scheduled time. I had to email the recruiter to ask what happened - they were "busy" and forgot. We rescheduled, but I had lost my interest by then.
