Interview
I had 4 rounds of interviews. 3 phone interviews with questions related to stats/probability, strategy/game theory, and strategy/exploitation respectively. The last round was the Superday and I had 4 interviews, each of them consisting of one game. Be prepared to apply your knowledge of probability and game theory to real scenarios. Remember that observation and sacrifices are important since none of the games had an analytical solution! You'll fail very hard if you're a perfectionist (that's what happened to me).
Interview Questions
It was a question at the on-site interview about horse betting on 2 horses with irrational audiences(they only bet on the horse that has a higher winning rate). You're allowed to bet on both horses A or/and B but without knowing which horse is the one that everyone bets on, what would be your strategy?
