Pretty hard interview, but the interviewer shares hints throughout the discussion so it's most important to share your thinking. Probability brainteasers and market making questions, no behavior questions in the first three interviews.

Question 1
Same standard market betting games and probability question. I am pretty sure they have the same set of questions that they permute all the time. Please just mug up a bunch of probability/game theory question do not overthink.

Interview
I was interviewed by a quant trader as a technical interview. I had two questions about probability theory. I failed the interview, very likely due to I made a mistake on the second one, though I was not given enough time to think about it thoroughly.
