I interviewed at Susquehanna International Group (Chicago, IL)
Interview
Aggressive behavioral and technical. Options trading question about different probabilities. Very aggressive technical with follow ups. Three Technical Questions and then follow ups if necessary. Follow up on behaviorals as well so be prepared and do not lie
Start with a math quiz ish thing, an hour long I believe . No idea what the percentage requirement is, you don’t get to see outcome. Then a 30-45 interview with a behaviour then some probability question. Followed by another technical interview. Still in the process
