    Quantitative Trader Interview

    Positive Experience
    Average Interview

    Application

    I applied online. The process took 1 day. I interviewed at Jane Street (Princeton, NJ (US)).

    Interview

    One math brainteaser and four probability questions that built off of each other. I got all of the answers correct with minimal assistance; however, I still did not receive a second round interview. I assume I took a little long to answer the questions (took a few minutes to answer 4/5 of the questions and ~15 seconds for one of the probability questions).
