Sorry to break it to you, but anyone who is still at Facebook at this point thinks they are at the top of the heap and a lateral move to maybe Google, Apple, or Microsoft would be worth considering if it included a bump in grade. Amazon is a place Facebook recruits from, it does not go in the other direction. [FB and Amazon have the same moral issues if you work there but the environment at FB is an order of magnitude better, particularly for mid-level engineers.]
