I think part of the problem with Google's hiring process is the attitude you're demonstrating here, where somehow even just interviewing with them is some sort of "privilege". Yes, I know they have to deal with a stupendous number of applications, and much of their process is a direct result of that sheer volume, but so long as people walk around with that kind of attitude towards them, they're given all the excuse they need to be imperious about it, to boot.
