First stage interview, pair programming with a senior for a problem related to his field. Complexity was added to the problem gradually. Great vibe and enjoyable chat, the task wasn't challenging per session, but it's much less clear what they wanted compared to other places.

I have only done the hackerank so far and got a first round. From my research, the interview process can consist of 1-2 Zoom interviews before an in person superday which typically consists of math (business case), technical, and a behavioral round.

Two or three probability/statistics brain teasers/problems that you have to solve. Topics include Markov Chains, EV, decision/game theory, branching processes, gambler's ruin, best decisions, optimisation. Interview with an actual quant.
