Colloquio
Applied and was asked for an interview the next day (delayed interview, however, because I was too early for the intern interview process). Had an interview a few weeks later. It was difficult. I was asked to write a memoized form of a function, evaluate its time complexity, then memory. Then I was asked to improve its memory cost. The answer, I believe, was to implement some sort of LRU stack (which I said some form of), however the interviewer seemed to zone out about 15 minutes until the end of the interview. I must have been too slow to answer or something, because he zoned out and I heard typing on his end towards the end, so even if I got it in the end it was already a no.
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.

Colloquio
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.

Colloquio
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.
