I applied online. The process took 3 weeks. I interviewed at Susquehanna International Group
Interview
Online application, followed by inital screening then online probability/numerical assessment. First round interview, including mostly mental math, standard expected value and bayes theorem questions. Overall not too hard, but be sharp on mental math.

I interviewed at Susquehanna International Group (Philadelphia, PA)
Interview
I received an online assessment for the role, and the entire test was focused on expected value problems and probability/logic-puzzle-type questions. Nothing was surprising in terms of content — it was exactly the kind of quant reasoning you’d expect for a data-focused role. The difficulty was moderate; definitely solvable if you’re comfortable with basic probability and EV calculations.
What was disappointing is that after completing the OA, I didn’t hear anything back. No interview invitation, no update, no rejection email. Just complete silence. It felt like the OA was being used as a broad filter, and even if you perform decently, you might not move forward simply due to volume.
