J'ai postulé en ligne. Le processus a pris 4 semaines. J'ai passé un entretien chez Jane Street (New York, NY) en oct. 2017
Entretien
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..

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

Overall, it was a pleasant interview experience. I answered a few personal questions and encountered one that was slightly confusing, but the interviewer was friendly, and the conversation flowed well overall
Probability questions, nothing crazy but quite open ended, they want to know your thought process and calculations. Pen and paper allowed but no calculator. No OA, a few rounds and got rejected. Zoom call with a trader.
