    Intern Interview

    Neutral Experience
    Difficult Interview

    Application

    I applied online. The process took 4 days. I interviewed at Jane Street (New York, NY) in December 2016.

    Interview

    Was asked if I wanted to take an online interview rather than a in person interview for first round. I elected to take the online interview. It was fairly easy, but I wasn't sure what to put down given the time constraints (a few slightly complex probability/expected value type questions in 30 minutes)
