Behavioral questions and then prob and expected value questions for the first phone call. Never made it to the second round though since I needed help on all the prob questions

Mix of behavioural and technical questions, with a focus on market making games.
For example make a market on the sum of two dice rolls. Also some questions involving options theory.

Consisted of an OA with 10 probability questions. pretty straightforward dice and coin flip problems for the most part. I think you get like 25 minutes or something to do it. Next was first round interview which was the same kind of probability questions but this time with a specific focus on casino games. Second round was market making questions, I would practice these as they as you a lot about logic, risk parameters, and how continuous versus stationary distributions change how you should bet.

Phone screen with probability and math questions conducted by traders. Pretty standard stuff but interviewer gave no hints so be prepared to explain and be firm in your reasoning. Green book and quant guide probably helps.
