Ho presentato la mia candidatura tramite l'università. Ho sostenuto un colloquio presso Jane Street
Colloquio
I applied through my college's online job postings and heard back in about a week to set up an on-campus interview. I was later contacted by HR to make a phone interview instead. The phone interview was by a software developer and was about 40 minutes long. He asked me various questions about OCaml.

There were many basic OCaml questions such as "What is the type of List.fold_left"?
The harder ones were:
1) Describe how you would implement a garbage collection algorithm.
2) Describe why this algorithm for garbage collection does not work: Counter incremented when a pointer to the memory is created, and is decremented when the pointer is removed. Deallocate when the counter is 0.
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.

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.
