Meta Project Manager interview questions

Recruiter reached out to me in July for my interest in facebook. I had given an interview last year and I think recruiter found my profile from there and reached out for a possible interview opportunity. It was a long and painstaking process and I wish I haven't accepted recruiter's interest in my profile. I had a pretty good experience with the facebook screening process last time but this time it was very unprofessional with a super disengaged recruiter. At the end it felt like a waste of my time. After the initial discussion with recruiter she came back and wanted to schedule phone screening, I gave her three slots but she didn't come back till 3 weeks, after couple of follow-ups she got back saying she forgot to enter my details in the system and asked for 3 slots again. I gave her the 3 slots, this time she was kind enough to schedule my phone screening. I had back - back two interviews one on Product Sense and another on execution. I had pretty good interviews, specially the execution round went really well. From there on the recruiter took got 3 weeks to get back to me with results. It was such a slow process that it almost felt like a sham, I started this process in July 1st week and by end of September I had the results from phone screening. My efforts are better spent elsewhere

Phone Interview with HR, Phone Internet with Hiring Manager, In-person Interview with 4 departmental employees, 30 minutes in segments. Overall questions/process was fair, but was not personally very impressed with attitude of (individual) hiring manager. Employees appeared stressed and overworked.
