Meta Senior Software Developer interview questions

Although I did not get offer, the overall interview process was very well organized, interviewers were friendly and helpful. As a feedback they said I've asked too few specifiing questions, and that's why I failed.

Interviewee - rude and aggressive and doesnt want to hear what you have to say. Very very very rude Sou Ind@n person. Always saying ur code is not optimized and saying why ur using BFS for binary level traversal. I did in log n though. This is the first time in my life somebody asked me why ur using BFS for binary level order and why queue. USE DFS. He said this is WRONG. NO BODY USE BFS.... Please dont take interviewees if ur NOT Interested in taking it.
