Completely agree with you - I frequently used to ask experienced candidates questions of the form, "tell me about one very difficult bug or performance issue encountered during your two years working on X."
Unfortunately, the number of flat-out liars on resumes is extremely large. Heck, I've even seen resumes from people I worked alongside at Microsoft who now claim to have done things that I did while there. <shrug>
Sussing that out is part of the interviewer's job, at least if you care about 1) whether you're hiring a liar 2) the skills that should have been gained if they actually spent two years working on X.
