J'ai postulé en ligne. J'ai passé un entretien chez Jane Street
Entretien
I only know the first stage (phone interview) because I've failed it twice. I had to write some code in an online shared text editor. Afterwards I got the opportunity to ask questions, which I made a lot of use of. I'm not sure what I did wrong because I think I only made some minor mistakes that are ones that any developer could make, so the only other thing I can think of is that maybe I asked a question they didn't like or too many questions - or maybe they didn't bother to look at my CV properly until after the phone interview.

Question 1
What is the behaviour of [a certain Java class that I used in my code] with respect to garbage collection?
It was a very quick and painless process. Recruiter very responsive, kind interviewers. High implementation and difficult problems, so failed onsite after 3 interviews and a Question and Answer Session.

Did not pass the initial coding round. I tried to explain my thought in details to the interviewer but failed to translate my thought into code. So far interviewer is very nice.

Entretien
My experience interviewing at Jane Street was definitely challenging, but also surprisingly collaborative. Instead of focusing only on whether I could get the right answer quickly, the interviewers were much more interested in how I approached problems and explained my thinking. I worked through a few coding questions involving data structures and algorithms, and there were also some probability-style questions that tested logical reasoning. The interviewers were clearly very sharp, but they were also approachable and encouraged me to talk through my thought process the entire time. When I got stuck, they would sometimes guide me with small hints so we could keep exploring the problem together. Overall, it felt less like a typical high-pressure interview and more like a thoughtful technical conversation with experienced engineers.
