Susquehanna International Group Quantitative Trader interview experience

The whole thing felt like a fairly standard quant-trading pipeline, with probabilities at the center.

Across the technical rounds, the content leaned heavily toward Green Book style problems and game theory, plus expected-value reasoning. The interviewers were nice and actually helped when I got stuck, which made the experience feel less adversarial even though the problems were still legit. I didn’t end up with an offer, and the most honest takeaway I had was that I was tested on fundamentals under interview conditions rather than on anything surprising or wildly different.
