Colloquio
Phone interview was very pleasant experience although we didn't move forward (they emailed to me after few days that currently they don't have position for me...).
All tasks I had to solve weren't hard at all, but because you probably haven't thought about them before the way they make you do, you may feel confused, but only at first.
Whole interview lasted for an hour and at the end interviewer (how is, of course, employed at Jane Street) talked about some projects they do and how they do ...

Using some functions they gave me which operate with cells in spreadsheets, I had to compute sum of an array. Later I had to implement by myself those functions: the trickiest thing was to implement the part when some cell is a sum of two other cells and some of those two cells is a some of some other cells and so on ...
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.

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.
