J'ai postulé en ligne. Le processus a pris 4 semaines. J'ai passé un entretien chez Jane Street (Hong Kong) en mars 2023
Entretien
First round phone screen, reasonably chill, write clean code and communicate well, they don't compile or run your code they simply tell you if something is wrong so you need to debug by inspection. Otherwise a really fun interview Final round consists of 3 interviews like the phone screen, a little harder, same deal: communicate well, write clean code, debug by inspection, etc. After the first 2 rounds they tell you if you're progressing to the 3rd round or not.
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.
