Everyone was always super nice and helpful during the interview, even if I made some calculation mistake.
First step was a bunch of games and math problems; they test reaction speed, dexterity as well as quant stuff.
Second interview was a game using dice, cards etc. and given a specific outcome, you find arbitrage opportunities to make money.
