Three rounds - two for technical, one for behavioral - all in one day over Zoom/Teams. for the first rounds, it was a typical probability/game theory type question about a game similar to blackjack. The game rules are described and a few basic questions are given to ensure understanding, and then every few questions, the rules are slightly modified to present a new situation. This mostly tested probability theory instincts (expected value calculation was involved). For the second round, it tested mathematical instinct by setting up a treasure map situation where at every turn you would have three different actions with three different outcomes, and you were challenged to optimize different situations given specific sets of variables
