Meta Staff Software Engineer interview questions

The process was smooth. Interviewer went through a couple of HR questions, and some follow-up questions. Coding was medium level difficulty, got 2 standard programming questions, both are from Leetcode

One phone screen, followed by 5 rounds of onsite. Phone screen was 2 coding questions in 40 minutes + 1 behavioral in 15 minutes. I had solved both the coding questions before. For onsite: 2 coding rounds, 2 design rounds, 1 behavioral. The coding rounds were okay, again standard leetcode. The design rounds were difficult because the problems were pretty large and the interview is only for 40-45 minutes. So you need to be very fast. Behavioral was also pretty intense. The guy was shooting questions at me non-stop. I barely had time to breath.
