In my short contract stint at facebook, my experience was that everyone I interacted with was overly territorial and wanted to be the "big swinging dick" as it were - their unwritten ethos on how to manage projects was bullshit, and after following my managers requirements to a tee - I was let go "because I was to engaged in the social events" (I literally played dogeball once. Never went to any other events) -- but I caught a VP in a baldface lie inadvertantly - and when I reported that his office project status was behind schedule he flipped his lid, and I believe had me fired.

He wanted to ONLY have all project status come from him - but he went on vacation, and I was required to get project status from the team involved - and when I did, I factually represented what I was told - that they were behind schedule - and I was let go.

Showing any interest in any area outside of my primary role was frowned upon heavily.
