I applied through a recruiter. I interviewed at Meta (San Francisco, CA)
Interview
First recruiter round, technical interview after 2 months. If you clear that you will have 4 more rounds, 3 technical + system design, and one behavioural. The interview process begins with a recruiter screen, followed by a technical round (often scheduled 1–2 months later). If successful, you proceed to four more rounds: three technical (including system design) and one behavioral interview.

Question 1
heap(kth element in the array) and queue(valid parentheses)
Interview was 45 minutes, 5 minutes of bs talking and then straight to the questions. You have basically 15 minutes per problem so keep that in mind when you're practicing at home. Set a timer, speak out loud while you're solving the problems and do everything you can to simulate the actual interview. Nerves getting in the way is a real thing to be aware of ("ll get back to why this is important). Anyways, interviewer was nice, he gave example inputs, assisted and gave hints. I actually answered both questions right and thought all was well. definitely thought would make it to the on site.
Passed the initial round and then rejected in the final round. 3 out of 4 persons said yes but but the overall decision was to decline my application. The final round was 2 technical, one ml system design and one behavioural.
