Attended first year program, got interview directly from program. Then had two technical rounds, rejected after 2nd round. Both around 45 mins long.

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.
