The process took 2 or 3 weeks, consisting of a few phone interviews and an onsite interview. The onsite interview consisted of about 5 rounds, each with 2 interviewers. Questions were difficult.

A question that is Jane Street-esque would be the following:
Suppose there is a game. You flip a coin again and again until you see 2 consecutive heads. What is the expected number of coin flips?
Follow up: What is the expected number of tails?
I had a phone screening call from a recruiter, they asked some standard probability questions, bayes rule, and expected value about dices. Overall experience was pretty good. Make sure you prepare your probability

Colloquio
Very smooth. Around 30mins first round 1hr for the second round. First round consisted of easier probability based questions. Second round was similar but harder and longer questions. The interview process if approached in a calm composed manner should be easier to analyse
multiple phone interviews and a full-day Zoom interview. Interviews got longer and longer over time, but every person was very kind and helpful with hints when I got stuck. The questions get harder as the rounds progress and generally don't have a closed form answer in the later rounds
