I applied online. The process took 3 days. I interviewed at Jane Street in Jan 2015
Interview
It was a first round phone interview that lasted about 30 minutes. Then a second round of interviewing. The questions were mainly competition math questions and basic probability. There was nothing too surprising. The questions mainly focused on prime factorization, number theory, base changing, die rolling, coin flipping, expected value, and optimal strategies.
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
