A very nice HR but very difficult questions.
Several mental maths problems. Then probability questions. If you were wrong, she'll keep asking you what's your probability of getting it right? If I let you bet on your answer on $1/100/1000/1m how's your answer?
Interview questions [1]
Question 1
Two teams A and B played football twice. Two independent matches. The average shoot of A in match 1 is greater than B. The average shoot of A in match 2 is also greater than B. So can we say the average shoot of A is greater than B in two matches together? If so, why? If not, give me an example. -------- Failed to give the example, but I believe that the statement is not right.
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.

Question 1
You are playing a one-player game with two opaque boxes. At each turn, you can choose to either "place" or "take". "Place" places
$
1
$1 from a third party into one box randomly. "Take" empties out one box randomly and that money is yours. This game consists of
100
100 turns where you must either place or take. Assuming optimal play, what is the expected payoff of this game? Note that you do not know how much money you have taken until the end of the game.
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
