J'ai postulé en ligne. Le processus a pris 3 semaines. J'ai passé un entretien chez Jane Street
Entretien
I applied through their website and heard back after about a week about the first phone interview. This interview consisted mainly of probability questions about dice and coins. After about another week, I had the second phone interview, which consisted of harder questions involving uncertainty.
Questions d'entretien [1]
Question 1
There was a Fermi problem that I found quite challenging.
They tend to examine the logical thinkers that can communicate clearly and concisely, and some problem-solving exercises intended to explore how you gather and apply new information, very different from other tech companies' interviews.
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.

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.
