Meta Software Engineer Intern interview questions

I have applied during on campus recruiting. I was asked to complete online programming challenge. After successfully doing that I got a phone interview. I was really well matched with the interviewer as he was sharing my interests and holding position I was interested in. The interview questions were very simple, however I didn't get the position.

It was a really fast and straight-forward recruiting process. I had a phone screen with a recruiter, then two coding interviews with Facebook Engineers with two coding questions each. Next day after the second technical interview, I got an email telling me that I've been accepted as an intern for next year.
