Applied online, contacted by recruiter immediately. Phone screen followed by 1.5 hour video call with hiring manager, then final round onsite - 3 separate 45min interviews (engineers, peer pms) and a 30min presentation to a panel of 4 senior product and engineering folks followed by questions. Recruiter feedback was everyone had been very positive but the hiring manager (male and brand new in product area) had a concern about one area I didn't include in my presentation (yet didn’t raise it in the follow up question session). I offered to have an immediate call or follow up meeting with him to cover it off, an elementary tech topic I'd tons of experience with, but it wasn't taken up. Really disappointing attitude. Recruiter was good at providing communication throughout process.
