Three interviews all including maths, probability (cards, dice etc). Quite hard, need to talk through answers with interviewer while doing the questions and they will help you get the the answer if stuck
Digital interview through zoom, one probability question and one (hard) brainteaser, 45 min, barely anything behavioral. I don't know how to prepare for the brainteaser well but the probability one could be practiced for.

Question 1
Dice game with 100-sided die, play against an opponent and the one who gets the higher number wins 1€ from the casino (not from the other person). Tie = no money. You get the option to double the number of your roll for 0.2€. In what interval is it worth doubling?
The process was overall quite smooth. It included several technical rounds focused on probability, statistics, and logical reasoning, along with some classic brainteasers. I realized I wasn't well enough prepared for the probability questions, which made it more challenging.
