What DHH does could absolutely be incorporated by Google. Angular => RoR, GCE => Saas, conference speakers => conference speakers.

Anyway the point is that even at a company like Google there's plenty of room for people that haven't memorized algorithms and data structures but companies that only interview on these sorts of things are missing out on them because they seemingly don't care or haven't figured out how to interview someone substantially different from what they normally hire.
