Try "Cracking the Coding Interview" by Gayle Laakmann McDowell. There's some pretty good coverage of what you might find in an interview. I think what struck me is the author has worked for at least three of the companies you listed, but never seemed to stay at any of them for very long - it makes you wonder if working for the big four is really all it's cracked up to be (pardon the pun)! Google has also created some interview videos you can pick up on YouTube. They are (obviously) staged, but are quite interesting and informative. Good luck!
