Normal process. HR call - 1st interview with qr about math - 2nd interview with senior qr about coding and stat questions. And finally rejected. Normal difficulty level, but you need to answer quickly and accurately. They love smart candidates.

Very well formatted, interviewers were respectful and asked reasonable difficulty questions (standard quant trader questions) that tested probability, statistics, and also general brain teasers. The interviewers were also very nice and explained their career choices well, as well as the firm.
