Recruiter, HM, Onsite with a Panel. Overall pretty standard questions around product design, intent, customers, etc. Was a standard PM interview but did not get through. Got feedback that I didn't have enough conviction.

The interview process was quite extensive, involving multiple stages over approximately three weeks. It included a call with the hiring manager, a conversation with the recruiter, a detailed case study assignment, and a rigorous six-hour in-person interview at the office.
