J'ai postulé en ligne. Le processus a pris 1 semaine. J'ai passé un entretien chez Jane Street en août 2016
Entretien
At first I applied for another position, but I got offered to interview for a trader position and I obliged. The interview setup process was very straightforward, I was asked a comfortable time and the call was right on time. Pen and paper are not allowed, you have to do the problems in your head and out loud. I had 3 interview questions, all of them were posted here already. I got quite nervous and gave a wrong answer, but the interviewer hinted that I'm wrong and gave me more time to think. The interviewer was very polite and answered some questions about the company afterwards.

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.
