(Non snark ahead) Could this be why working at Google is no longer the prize it once was? And why developers would rather go to Facebook, Twitter, Dropbox, et al?
(Completely idiotic response ahead) Umm, really? Every day I see thousands of developers who would rather work in Google than Facebook... :)
(Non snarky response) I dunno. I joined Google in 2008, and as far as I know Google was always like that. So, unless you claim developers have preferred Facebook etc. to Google for more than 5 years now, it's probably not related to the interview process.
I chose Facebook over Google two years ago (despite a more lucrative offer from Google), because I wanted to go where I could have more of an impact. The interview processes are nearly identical. One of my go-to questions was a question I got asked at Google, actually.
