Applied online. Recruiter reached out via email to set up phone interview. Interview was tough. Mostly math questions and probability concepts. Some brain teasers too. No behavioral or why Jane Street, just math. If you get guided questions, you are done for.

Interview
Attended first year program, got interview directly from program. Then had two technical rounds, rejected after 2nd round. Both around 45 mins long. First one definitely quite easy compared to 2nd one. Interviewers very nice and considerate and want to see you succeed which definitely made the experience way better.

For first round I got 2 questions, one based on a game against a single opponent involving a pair of die. The other question was more a solo game, involved some EVs / playing optimally when playing this game ie asked me how would you play this game, if he game changes slightly by now having X and Y, what is the EV of this new game.
Interviewed for two rounds. I passed the first round last year so was able to continue immediately with the second this year. Probability/game theory questions. The interviewers are friendly and helpful.
