2 phone interviews. They both asked some personal questions at the beginning and 3 math/probability questions at the end. The math questions were easy, but there was one question with a lot of details/things to remember.

4 rounds of interview 1- recruiter background check 2- HR to screen candidate/ behaviour question 3- trader - technical questions 4- head of operation - heavy operational stuffs Overall pretty good. Last round you really need to prepare they will ask you to solve issues on the spot under pressure by throwing a lot questions
