First round interview consisted of two logic questions and two knowledge questions. Only got 2 right but moved on. Second round was much more difficult, several technical trading and finance questions. Got maybe two-thirds of the questions right but failed to move on.

1st round technical easy math/stats, 2nd round technical harder stats. Focus on math/stats problem solving. Somewhat hard to prepare for, just know your probability well. Interviewer refused to explain answer to technical question when asked for an explanation.
