After the recruiter call, about a week later I had a technical screen where they walked through my resume and then asked me to do a LeetCode-style coding problem at a medium level. The interview felt like a straightforward test of whether I could translate my background into clean, working code.

Eventually I reached the next step, which sounded like it was heading toward a superday format. I didn’t get to complete the onsite portion from that timeline yet, so the process stopped at the point where I was waiting to see the final round. Even though I didn’t finish, the overall vibe stayed pretty standard: resume discussion, then medium coding, then a bigger final loop.

My process started with an HR call where the focus was my background and fit, and then I moved into a technical interview with a quant researcher. That technical session had a LeetCode medium question, but it quickly turned more “researchy” afterward with a Markov-chain style problem about expected steps using a cube-like setup.

What I remember most was how they followed up on the math and also expected an efficient way to simulate the idea for general dimensions, not just the toy version. The whole interview journey felt pretty standard for a quant researcher track—coding first, then theory, then a deeper follow-through on modeling and computation.
