Screening -> Online tests in math (many problems on a variety of topics) and programming (3 easy problems on data parsing and filling in gaps) -> 3 technical interviews (math, programming, and DS/finance), usually a few simple warm-up questions and 2 more difficult problems to test the depth of knowledge -> interviews with teams, talk about your experience, scientific work, then questions related to the specifics of the team you are applying for, you need to come up with hypotheses about the data -> rejection

There were 5 rounds in total. It began with a 30-question math assessment on HackerRank, followed by two face-to-face interviews focused on probability. Next, I completed a 24-hour take-home test and presented my findings. The process concluded with a final interview with a manager to assess cultural fit.

Very hard interview, I suggest you to study hard linear algebra statistics probability and more more more more because again it is hard very hard and I need to hit word qouata here
