    Application Details

    I applied through college or university – interviewed at Jane Street.

    Interview Details

    Submitted resume through school recruiting website, learned that it had been accepted for an interview a few days later. Came in for a 30-minute one-on-one interview. First couple questions were mental arithmetic, and then there were two/three probability questions. Essentially you only get to the next round if you successfully solve all of them.

    • The classic 5 pirates/100 pieces of gold game theory question. Did not expect it.   Answer Question

    Application Details

    I applied online – interviewed at Jane Street in October 2014.

    Interview Details

    3 Phone interviews, and then an on site interview. Pretty much all probability / expected value. Lots of dice games. The on site interview was like 4 1-hour long interviews, where they gave you poker chips and let you trade on different games (aka guess the expected values). Overall it was really fun, and even though I didn't get the offer, I really enjoyed the entire interview process.

    Phone interview. Woman called and asked some basic questions about mental math and some coin flip stuff. They seemed arrogant and as such I did not want to pursue the job.

    Application Details

    I applied online. The process took 4 daysinterviewed at Jane Street.

    Interview Details

    Got asked 4 quantitative questions. They were progressively more difficult. I answered the first 3 correctly, without much time used. The last question, however, I couldn't figure out. The interviewer tried to help me, but between his accent and the noise coming from the background (his side), it wasn't useful. After about 15 minutes, he ended the interview.

    Interview Questions
