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

My process began with several technical interviews—about four or five—conducted by engineers.

After those, there was a team matching step.

For the internship path, team matching could vary between different groups, and the follow-up interviews sometimes leaned technical while other times they felt more like culture-fit conversations. The technical questions were LeetCode-style overall.

I didn’t end up getting an offer. What stayed with me was the variation: even after the core technical screens, the matching phase could feel like a shift in evaluation style, so it wasn’t just about solving algorithms anymore.
