I've also been doing interviews for a few years at three different companies, and I've encountered it. It depends heavily on the quality of the recruiter. Good recruiters will attempt to filter out complete duds, bad recruiters will pack a clown car full of "rockstar candidates" that just wasted my time. There was one particularly bad instance where a guy with 10 years of experience and a masters degree got stuck for an hour trying to write a for loop. With unfettered access to Google.
