Meta Product Designer interview questions

Overall this was a terrible experience. The internal design recruiter at Facebook cancelled, missed or rescheduled a total of 4 times over the course of 3 weeks. Once I was cancelled on an hour before the call. Another time I was waiting for the call and it never came, then when I emailed to find out what happened I was told they double booked me, or another time they got the wrong day. The attitude throughout seemed like I had to be on their schedule, and they were doing me a favor almost, even thought they'd repeatedly tell me how interested they are in my work. As 'interested' as they were, recruiter had no understanding for what I specialized in or what my company did. They never asked if I was interviewing with anyone else (which I was, two other big tech company in SF). Finally when I did the in-person interviews, those went as expected. Then again following the in-persona interviews they didn't reach out to me with their decision. I had to contact them a week later to find out that they had decided to move on. This process we demeaning, extremely unprofessional, and compared to all the other companies I interviewed with, was probably the most impersonal. All my years in the bay, I've never experienced anything like this.
