Meta Software Engineer interview questions

It is an onsite interview when all group interview are not available and can't be rescheduled since the hiring season is ending. We had serial engineers as interviewer in turn. They didn't had our resume and didn't know anything about us.

I had one on-campus interview the week right after our career fair. I made it to the second round and had one on-site interview at the Menlo Park location. They gave us a tour of the campus, fed us, and held an Oculus demo.
