Meta Software Engineer interview questions

Very technical questions. Be sure to review your data structures, sorting algorithms, and syntax without a reference. They don't care much about syntax, but it might trip you up during whiteboarding. They were extremely friendly, put you up in a hotel and take good care of you during the interview. I think there were many opportunities to ask questions and learn more about the specific problems they're trying to solve.

I was applying to Facebook through a friend that is working there. I was first contacted by a recruiter who asked some technical questions. I was next contacted only 2 weeks later and a phone interview was set. The question was relatively easy, but I was stressed and couldn't think of a way to make it more efficient.
