J'ai postulé via un établissement d'enseignement supérieur ou universitaire. Le processus a pris 1 jour. J'ai passé un entretien chez Jane Street en sept. 2010
Entretien
Phone call. Some mental calculation and probability problem. It is around 15min. After that, the result will be given. During the calculation, you should not only give results but also the idea. He would like to check your confidence in your calculation. I think it is better to show your confidence strongly.

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.
