Meta Software Engineer interview questions

I was referred to by a friend of mine interning at Facebook. A recruiter then set up me two phone interviews, each lasting about 45 minutes. The interviewers were very friendly but I was too nervous because it was my first time to interview, so I performed bad at both interviews. After that I got an email that I was not a good fit for the position.

Was contacted via LinkedIn / StackOverflow Careers, sent in CV, got a call from a person to discuss a few points on my CV. Was scheduled for technical interview via skype. Was quite nervous and screwed easy questions around which data structure to use for the posed problem of finding all connected components in a bitmap (0/1) picture. The interviewer was quite nice and forth coming but I wouldn't have given a further call to myself and that's what he recommended.
