This was the first stage phone interview for a internship programme. It took approximately 30 minutes and began almost immediately with actual questions. The interviewer was probably one of the most polite and friendly person I've ever encountered during any application process.

Question 1
Fairly predictable dice questions. The only difficulty was that interviewees were not allowed to use paper and pen. The key idea throughout all of the questions was to define an optimal strategy for a game which score was based on a product of numbers on dice.
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

Question 1
Expected value, if throwing a dice, 2 dices and 3 dices with option to reroll.
I applied online. I interviewed at Jane Street in Nov 2022
Interview
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
