J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Jane Street
Entretien
Two interviews over the phone. Most of the interview consisted of solving mathematical problems. The interviewers also described some of the work they do. The interviewers were very pleasant and the questions were challenging but fun.

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.
