I'd consider myself average at best and got job offers to two of those companies. I still work at one of them and have been promoted (so I can't be that terribly bad).
Honestly, reading cracking the coding interview and the algorithm design manual go a long way to summarizing relevant information you learn in college. Knowing how to write Python coupled with working through those books is probably enough to get hired like maybe 7/10 times. (I say 7 because a bad interviewer can sink your interview and there is nothing you can do about that).
My point being, is that the people that work at those companies are not dumb but that they are for normal people too. I wouldn't not apply just because you think everyone is somehow really smart.
