My advice? Don't sweat it. I didn't get an offer from Amazon after the in person interview. I was pretty bummed, to say the least. But I did end up getting a job that pays just as well, in a company just as cool, in a position that might actually be a better fit.

If you are good, keep going. You'll find what you are looking for. Just don't get too caught up in the "it has to be Google/Amazon/Apple/etc" mindset. There are a lot of other great jobs and companies in this market for technical skills.
