I applied online. I interviewed at Susquehanna International Group (Philadelphia, PA)
Interview
OA, Recruiter screen, technicals, superday. Easier Online Assessment relative to other firms. Recruiter screen is a vibe check. Hard technicals and superday for sure as one would expect at a competitive quant firm. Prep probability, brainteasers, etc
Interview questions [1]
Question 1
throw three marbles at a tic-tac-toe board. Probability it makes tic-tac-toe?
Had an OA two phone interviews then a zoom interview. All rounds were probability questions or pretty standard math problems. they reuse questions pretty heavily. People I talked to were all very nice. good culture seemingly.
