If you have not done so already buy a copy of Cracking The Coding Interview and take a few weeks off applying anywhere to work your way through it. Most modern interviews are tests of how recently you have read this one book. Good luck!
That's not much of a problem. At least not for me. I pass most of these interviews. But still...
Anyway. It's probably too early to get to conclusions but I just wanted to highlight that it has been abnormally hard, long and at times surreal up to now.
