United StatesPosted Jul 2025 · Candidate report, summarized by Dataford

I went through a more traditional multi-stage quant process: a probability screen, then a coding round, and eventually an in-person superday with a behavioral at the end.

The superday itself felt like a blend of quantitative trading style interviews and software-engineering style evaluation, which made it more varied than I expected.

On the earlier technical rounds, coding didn’t feel like heavy algorithmic competition; it was more about reasoning, system thinking, and being able to walk through what I was doing. The quant/trading portion swung back to probability and brainteaser-style problems, where the difficulty came from having to think quickly while staying coherent under time pressure.

By the time I wrapped up, I felt like the day was pretty fun
