Entrevista
I applied online and got an email about two weeks later. The initial interview was a phone screen. One of the traders called me from his desk and the interview lasted for about twenty minutes. He asked me a bunch of probability questions and a few brain teasers. He then turned the time over to me to ask him about Jane Street. He was really nice and helpful. I got stuck on one of the questions and he guided me through it.

Dice game where you get paid the number that you roll. Expected value for the first roll, expected value for if you get to choose to roll a second time, and expected value if you can roll up to three times.
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

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
