Three phone interviews and a day of interviews onsite. First phone interview was very short 10 - 15 mins with two short questions all others were about an hour long. Process ran very smoothly

They asked mostly probability and game theory questions. On-site consisted of a lot of betting games. Very collaborative experience when working on through questions. Overall I enjoyed the the interview experience.

First question was on dice rolling, you get one dollar if your roll is higher than your opponent then you win nothing otherwise.

Final round consisted of five rounds in person. Standard market making game on sum of 4 cards with side bet for arbitrage (40 card deck), then one coding (simple, not leetcode esque), then one data analysis, and two more math/trading esque games

For side bets, you can do on next card being red/black or higher/lower than 5.5 for 1:1 payout. (you need to figure out how to use this for arb)
