Facebook interview experience

Recently had an interview at Facebook for a management position (tech track). I think it is worth sharing that experience. Interview was with some director of XYZ department (does not matter). Let's start with the fact that the interviewer yawned first time about 5 mins into the conversation. He continued doing that pretty much until we parted. The questions were very typical, describe the time when... Blah. At some point he seemed to be upset that I haven't had an experience of when I had a conflict between me and a next level manager (i don't consider healthy heated discussions as conflicts). When I suggested I could talk about a hypothetical scenario - he laughed. (I felt like it was "You have not seen life, kid" type of response ..though I am pretty sure we were same age). He moved onto the next question... The funniest part was at the end when I flipped the tables and asked him: now when I described you all my experiences especially in connection to promoting people , how do they compare to FB practices?! He really didn't expect that sort of question and just mumbled something like "similar". Then I asked him to describe his career progression at FB. His answer was "The group was over 100 people and they needed to split it so they made me a manager". :)) Then I tried to stick to a professional continuation ..."But by that time I assume you have already had a track record of successful projects..." His answer: "Not really". End of the interview. Today I received a NO from them. I am glad I won't be working at FB for that department. I really hope this was just a bad day/manager and FB is not like that.
