I am not looking externally until I'm sure I'm done at AWS. I've done 80+ interviews here, and I'm consistently amazed by what drives people to say "The candidate wasn't up to the coding bar". As far as I can tell, you are almost never up to the coding bar. I think we interview so many people just to remind ourselves that if we leave, we aren't getting back in.
Just to head off the "So why don't I argue for change?" questions, I'd rather work on self improvement than fight tooth and nail to make the hiring process a little bit better. I'll let somebody else add that to their promo doc.
