Canadian Submitted my interview in December 2011 Received a call end ofJan/beginning of Feb from a recruiter. Went through an initial phone screening with both some general and canned technical questions. After that heard nothing so I assumed I didn't meet initial criteria. Beginning of September or so I received an email from a recruiter with renewed interest. Again went through an initial "pre-screen" phone interview. Followed up by 2 more technical phone interviews. Finally received an invitation to an on-site round of interviews. Was flown to San Francisco for a 5 hour interview. FB covered all costs. It was definitely challenging!! Which is good when you've been in a senior level position for a number of years. Was first introduced to a "recruiting coordinator", followed by "technical program manager" (project mgr). After that came a VERY challenging individual who (being an ex Cisco product engineer) asked some very in-depth technical/theory/text book questions, and did his best to mix you up by questioning answers and presenting potentially wrong answers to make sure you knew your stuff. Have to admit it worked and know I had a couple of epic fails! Lunch with the technical recruiter and a tour around the campus. Bit of a "get a feel for you" session. Following lunch was another 2 technical interviews. Both again very challenging. A lot of "how would you design a new campus network" and "how would you troubleshoot this" questions. Etc... Finally was the interview with the hiring manager. Great guy. Questions about thoughts on change control, itil, working in an environment where there is a limited subset of the former, etc... Some other general "how would you deal with" personality questions. All in all very thorough. Having spent many hours on the other side of that table looking for the right candidate, a job well done. They'll no doubt find exactly what they're looking for... unfortunately I wasn't it (still not sure why, but the other guy was "a bit better of a fit" in their words)... Either way, it was a great experience, and I still have my day job which is pretty awesome in and of itself, just thought facebook would look good on a resume!!

Made my way to Facebook HQ for the grueling 5+ hour interview process. Met head recruiter, and introduced me to the first interviewer, who was from a different part of the organization, they said they wanted to get a perspective of me from someone on the "outside" What? Next person was the toughest. Instead of interviewing me, he basically wanted to show me exactly how much "he" knew about each topic. We spent more time going over what he knew, rather than how much I knew! Next couple of interviewers were very nice and asked "reasonable" questions, which I answered correctly. There were only a few that I said I would have to come back to, which I did and again I answered them correctly! I then met with the group manager, who was very nice, not technical at all, but asked me situation type questions about conflict management. You know the questions about how you handle tough people who think their ideas are the "only" good ideas, and other similar questions. So, overall I know for a fact the first interviewer had his mind made up even before we started the interview; arms crossed, stern look, higher-than-thou attitude. I didn't get the job, even though everyone else wanted to hire me, the first interviewer had it in for me for sure. The manager even asked me if I need to give the standard two week notice and basically asked when I could start. So I was shocked when i got the "we have no position to offer you at this time" email.
