Thing is, you can get the 'fake' programmer even with algorithm tests since they are only looking through a keyhole at someones overall employability. For many (most?) jobs work ethic, attitude, and don't be an asshole are all more important after a minimum programming bar is met. Admittedly I've never had to hire at Google/MS scale, but my best luck hiring has been like you said - talk to people and be up front about expectations and that we fire if needed.
