Domande di colloquio [1]
Domanda 1
A and B in a game. Each choose a different number. Roll two dice, take the sum. The one closer to the result wins. Go first or second, choose which number?
Many rounds of brainteasers, some of which are more rapid fire in nature and others which require you to flesh out a detailed answer to a complex problem. Be well rested and well prepared!

Colloquio
mostly maths probability questions - a lot of conditional probability, relatively easy in the first round, but you need to think out loud - you need to be really fast

4 rounds in final. The first one is market making of cards. The rest are especially designed games. The interviewer may ask added question along the playing of the game
