Meta Software Developer interview questions

I was referred by someone who worked there. I had a phone screen and was then brought onto campus for a day of interviews. There were 3 interviews back to back, 2 were technical and 1 was behavioral.

Phone Screen interview: The interviewer asked a leetcode hard question. Explained my thought process. Wrote Pseudo-code and then coded. Was running fine but was missing some corner cases. Didn't had time to run it on test cases. Asked a few question from the interviewer at the end.
