I applied through a recruiter. I interviewed at Meta
Interview
I have interviewed with facebook 3 times. every time they ask the same stupid question given an array of integers, find 3 integers that sum to zero. as many as 3 people from HR get involved to schedule a simple phone screen. and even after solving the problem in O(n^2) time, i did not get any on-site with them.

I applied through an employee referral. The process took 2 months. I interviewed at Meta
Interview
Everyone was really cool, got 3 interviews, one of which was partly technical and partly non-technical. The non-technical interview also has a small coding part at the end. The two others can be either completely coding or 1-coding and 1-design. The questions were all ones I hadn't seen before after practicing for a while, but I mostly found them simple-to-average difficulty, except one which was pretty tough, that I managed to crack a couple minutes in.
I applied through college or university. The process took 3 weeks. I interviewed at Meta in Oct 2014
Interview
Met the recruiters at the university carer fair and got a call a week after that. Had my interview on campus within that week. Got back my results 2 weeks later. The overall process took less than 3 weeks. The interviewers are friendly and will give hints in between to keep you getting closer to solution. This was a 1 on 1 interview and coding had to done on white paper. The questions are straight forward but need to take into consideration all corner cases when giving your algorithm. Also the code needs to be clean, so think carefully before starting to just code. Also practice writing code on white paper as when you are doing it you tend to scratch out code in between and that reflects bad.
