United StatesPosted Apr 2025 · Candidate report, summarized by Dataford

I had an interview where the interviewer was very friendly.

We both started with self-introductions, and then I jumped into a live coding problem in Python. The coding blended into basic statistics, so it wasn’t purely algorithmic—it was tied back to statistical thinking.

The question felt fair overall, but I ran out of time, which was frustrating because I felt like I understood what was being asked. I didn’t get an offer, and the main thing I remember is that even with a reasonable problem, the timing mattered a lot. When I finished, I felt I left value on the table simply because I couldn’t complete the full solution path.
