applied online got an interview the next day. passed the first round waiting for the second round. The interviewer is nice. She did not ask a lot about my background. Lots of mental math and probability questions. The questions are not that tough. no pencils and paper for the first round.
Domande di colloquio [1]
Domanda 1
Basketball player A and B. Game 1 and 2. In both game, A has a higher shooting average than B. Is it possible that B has a higher overall shooting average. Give an example if possible.
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
