Interview
The whole process was a total mess. I applied for quant research intern position but the HR emailed me for trading intern position and the interviewer was interviewing me for trading full-time position. The interviewer was busy doing his own work and remained silent until I asked him to say something, twice. I could also hear a women laughing and talking next to him and computer saying "large incoming transaction" or something. What a good experience getting to know JS trading floor!
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

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
