J'ai postulé en ligne. Le processus a pris 4 jours. J'ai passé un entretien chez Jane Street
Entretien
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.

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.
