Meta Software Developer interview questions

Spoiler: This was my second time doing a Meta onsite with no offer. A Meta recruiter reached out to me, as they do every year, and invited me to do a technical phone screen. I passed and went to the onsite. I didn't hear back for like 2 weeks so I contacted my recruiter a few times for potential feedback, since I thought I did well, and a request to possibly be down-leveled (this was mentioned to me as a possibility during my prep call) but was ignored and got an automated rejection email. They also didn't honor my request to speak with someone at Meta about the company, which is an option in the candidate portal. Bad experience. The coordinator also rescheduled my onsite 3 different times. I'm kinda over the idea of working at Meta now.

initial phone screen, technical coding interviews, and a final onsite round with system design and behavioral questions. interviews were leetcode medium-hard and onsite involves behavioral interview with management general questions such as working with team, disagreements, project deadlines ect
