Very straightforward. First interview was a nice get to know you. Excel and Odds test before the second interview. The math involved wasn't explicitly mentioned before taking it, just need to know conversions. Second interview had a few questions I wasn't expecting, but nothing that didn't make sense.

Series of Excel and Sport Betting related tests, then interview with the head of the sport trading team and the head of the data team. If you get through that stage, you get through to an interview with their boss.
