Meta Product Manager interview questions

I was contacted by a recruiter via linkedin who then set up a phone screen. Basic phone screen questions like "Tell me about a project you worked on recently?" They are looking for you to describe a complex project by breaking it down into simple components. After the phone screen the recruiter emailed me saying they would be moving forward and set up a video interview with a project manager on the team. Also, very general questions like "why facebook?" and again asked for me to explain a project I recently worked on. Also asked questions like "How would you pick members of a team?" Basically looking for answers that describe how you 1. find out what people are working on, and 2. if you pick individuals to make a team vs just picking individuals. After the video interview, the recruiter emailed me saying I was invited to an onsite interview and set up a time. Gives you the names of everyone you will be speaking to and their title. Highly recommend looking them up on Linkedin and preparing a few no work related questions about their background. The onsite is tough, as it lasts all day an involves multiple back to back interviews. It can be a bit draining and by the end of the day I started to lose my ability to articulate myself well. The question were simple, but difficult to answer because they are things I generally do instinctually and haven't had to articulate before. For example "How do you ensure you have communicated something effectively?" On the spot, it was a bit difficult to answer, but given some time to mull it over I would have had better responses.

A few weeks after I applied, I had my first call with the recruiter - very simple, basic Q&A. Three weeks later, I had a 30-minute phone interview with the hiring manager who arrived late to the interview. More high-level, talking about my background, how I approached roadmap prioritization, taking features from idea to lunch, what metrics did I monitor, and how did I know what actually impacted those metrics. I heard back one week later that I would be moving on, and it took another week for the recruiter to respond to my availability. At this point, I had offers in-hand from other companies and asked multiple times to accelerate the process since I would need to get back to the companies I had offers from, but it didn't seem like she even read my email. I finally had my second-stage interviews three weeks after my first-round. I had 2 video calls with an engineering manager and a PM. The PM was nearly 10 minutes late to a 45-minute call. The questions they asked were pretty boring and uninspiring. I didn't really get a great vibe from the interviewers - almost felt like they were arrogant. Then, almost two weeks later, my recruiter finally got back to me saying I wasn't moving on. All in all, the process took more than 2 months from my initial application and I still hadn't even made it to an offer stage. My recruiter was completely irresponsive. At each stage of the process, I probably sent her 1 email every 3 days, and sometimes it took her more than 2 weeks to reply. Overall, a completely terrible process. I had an irresponsive recruiter, and late interviewers who asked questions that I felt didn't accurately showcase my skills, strengths, and prior experience.
