New York, NYPosted Jun 2025 · Candidate report, summarized by Dataford

My process started with an OA that included basic probability and pattern recognition, then I went into a phone interview that leaned heavily into probability as well.

The overall feel was that the early stages were about filtering for the fundamentals.

The hardest part came later: a final round market-making interview. It wasn’t just a math puzzle—it was structured with partners who were actively checking whether my strategy was rational. That forced me to be very clear about how I was thinking and how the pieces connected.

I didn’t end up getting an offer. Still, the market-making round was the defining experience because it pushed beyond “solve this probability question” into “justify the trading logic,” and that difference made the difficulty feel
