The process started with an HR call about my background and fit. I then had a technical interview with a quant researcher. It included a LeetCode medium question, then shifted into a more research-oriented problem involving a Markov chain and expected steps using a cube-like setup.

What I remember most is that they followed up on the mathematics and also wanted an efficient way to simulate the idea for general dimensions, rather than only solving the toy version. The process felt fairly standard for a quantitative research track: coding first, then theory, followed by deeper questions about modeling and computation.

I was later invited to a superday with several interviews back to back. The full timeline felt like about a month, and the day focused on topics connected to my resume and on how I approached statistics and quantitative problems.

Location: United States. Overall feedback: Neutral. Offer status: No offer.
