    Difficult Interview

    Application

    I interviewed at Jane Street in June 2018.

    Interview

    Very friendly interviewer. Very nerve wracking interview. Doesn't help when your father decides to have a loud phone conversation directly behind you during the interview. Extremely distracting.

    Difficult Interview

    Application

    I applied online. The process took a week. I interviewed at Jane Street in June 2018.

    Interview

    I applied online through a their website. A day later, I got an email asking me if I was interested in applying for the Trading Desk Operations role, and if I was then they would send me a set of exercises. The exercises were based in Excel formulas and calculating haircuts and came with documents explaining the problems and PDFs to be used when answering. They asked me to send them back in 2-3 days. I had never calculated haircuts before, so I wasn't really surprised when I got an email a few days later stating I would not be moving on in the process. Still, each email was prompt and positive, so it was a good experience either way.

    Difficult Interview

    Application

    I applied online. The process took 2 weeks. I interviewed at Jane Street (New York, NY (US)) in May 2018.

    Interview

    Completed a worksheet. Then had a phone interview. Then went onsite for several interviews.
    Phone interview and email correspondence were great. The onsite visit was disorganized. There were complications with the travel and lodging arrangements they'd made for me which caused quite a bit of stress. Once I arrived at the location the onsite continued to be a bit disorganized, though not horribly so.

    • For the worksheet they gave me a packet with information on stocks and I had to summarize it and apply the information to hypothetical situations.   Answer Question

    Difficult Interview

    Application

    I applied through college or university. The process took a week. I interviewed at Jane Street.

    Interview

    Applied through the university and got an email with data tests. Excel files and 3 pdf explanations. It is pretty tough to understand the logic. The calculation on Excel is not difficult and you are supposed to know VLOOKUP etc. The challenge is to understand the question.

    I applied online. I interviewed at Jane Street.

    Interview

    I submitted my resume online, and was contacted a few days later to interview for the Trading Desk Operations position. I was asked a time and date when they could send some excel exercises, to be completed in 2-3 days. I sent them back within 3 days, and got a rejection e-mail shortly after. Exercises were not necessarily hard, but tedious and very finance-involved in terms of context, while the context needed is provided through pdf files and explanations.
