J'ai postulé en ligne. Le processus a pris 2 semaines. J'ai passé un entretien chez Jane Street
Entretien
Two phone interviews, probability questions, pretty tricky. Interviewers were both very nice/humble, gave helpful hints along the way. One guy gave some advice: computational speed will only take you so far and won't impress Jane Street in the long run. Better to take longer and get the questions right than try to speed through the calculations and mess up.
Questions d'entretien [1]
Question 1
You roll a die and get the amount you roll in cash. How much should you pay to play this game? What if you don't like your first roll and are allowed to roll exactly once more (but you must take what you get the last time)? What if you can roll up to thrice? Infinitely many times?
Initial application and online assessment. Had a first round behavioral interview where they asked me about myself, my experiences, and a couple of brain teasers. The interviewer was very nice.

Entretien
Phone interviews (at least 3) - questions were of mixed difficulty (some pretty hard) but the interviewers were friendly and they gave helpful hints. Kind of fun - review probability and game-type questions.

I first applied in google form answer basic questions about me and with that I had to upload my resume and transcript. I don't remember after how long I got an interview time to choose and did my first round of interview.
