Meta Product Manager interview questions

Initial telephone screening and then an on site interview. On site interview is two separate sessions on product. Well designed and clearly explained what is expected out of the session. Types of questions asked and how to answer them.

Got approached from internal recruiter via Linkedin. The first interview was a phone interview with the recruiter asking typical HR related questions to gauge my interest. Followed with a half-day onsite (had the option to do via video call but I preferred not to) having 2 one hour interviews with product managers. The first interview was with 2 product managers (one of the them mostly listening in) and the second interview was with 1 product manager. Questions were typical whiteboarding, what-if product related scenarios which I enjoyed. I think I did fairly well although I was ill at the day having slept very little so I underperformed and I felt there were areas I could have done better in. I left feeling 70% positive I would move to the next stage. I waited for a couple of weeks to hear back but I never did so after following up with the recruiter a few times, he told me that they wouldn't proceed further and it took long for him to get back to me because it was 'close'! I had asked to receive further feedback and I never did. The recruiter never called me back (even if we tried to schedule time) and additionally when I asked 'well can you at least give me a few feedback points via email' I received nothing. Really negative experience which I didn't expect from a company like Facebook
