Meta Developer interview questions

The FB recruiters were very on-the-ball and determined to get me to campus, and worked with me every step of the way. They flew me out, put me up in a nice hotel, and helped me know what to expect in the interviews. The process consisted of four interviews, broken up by lunch. Two "ninja" interviews (coding), one "jedi" interview (personality and values), and one systems design interview (whose cool name I forgot). The questions were tough, but fair. They definitely have a preference for code questions that combine data structures and creative thinking. My only complaint about the process was that they would spend a little too much time prior to starting the coding question asking me about my OS knowledge (I interviewed for a mobile job), and that left me pressed for time (sometimes) on the actual whiteboard coding.
