Don't worry about the interviews if you're able to have a conversation in English. The interviews are there to weed out the people that can't communicate. There are some technical tests that can be daunting, because they're a bit skewed towards algorithms. I had to take the tests twice actually because I simply wasn't able to pass it the first time, outside of the US people aren't as fixated with algorithms but I still think it's a fair test. You can retest in x months unless you really painfully screwed up some part of the hiring process.

Make sure you're properly prepared for the tests, have your environment set up. My mistake was to use a Playground for a live coding test that would completely screw itself up once the code I entered became more complex. Very painful.

I don't think they only hire the best of the best of the best but anyone that gets through their hiring process is definitely a useful programmer, no doubt.
