I had one phone interview and four on-site interviews: two coding, one cultural plus coding, and one system design.
My experience suggests that I should not have wasted my time with Facebook. It seems they interview people without giving them offers. I had a perfect day at my on-site interview. I heard a few others had similar experiences. None of us received an offer.
In my case, two of the interviewers seemed surprised by my answers, and I finished 15 minutes before the allotted time, chatting for the remainder. One interviewer even remarked that Facebook should hire fewer people to ensure enough challenges for current employees.
Recruiters at Facebook are also terrible. They respond to emails with template answers and unfortunately have very low technical knowledge.
