J'ai postulé en ligne. J'ai passé un entretien chez Jane Street en mars 2013
Entretien
Very prompt on the interview process. Get back to you fairly quickly. First round is usually easy but given that it's easy, they're brutal on quality. They expect you to have near perfect solutions or atleast be able to fix things very very quickly. Speed and efficiency are absolutely key,
The interviewer asked me some probability questions, felt kind of competition mathy. The interviewer was friendly but I got stuck on the math. It doesn't seem like it was meant to be too hard if you're familiar though.

Question 1
They asked some probability questions, a little tricky if you don't have any familiarity
first there's a 10-15 min call with a recruiter (another form of screening i guess) where you talk about your background and experiences. then if you pass that, an online interview. if you pass it too, there are 3 on-site interviews (they pay for everything), 2 before lunch and one after.
I was given a tree problem. At the start, I asked a few clarification questions. While coding it, the interviewer gave me some hints on how to better implement it. Was able to solve it. Did not get to the next round.
