Our process 'weeds out' candidates as soon as we know that its not a good fit. This in reality saves the candidate ( who may be interviewing at other places as well as working like you mentioned ) as well as our time. The 7 hour number keeps coming up, and seems like a lot, but very few candidates actually spend that much time. And, most of those are actually hired.

We've tried conversations as well, but unfortunately, it is very difficult to objectively measure them into what will make the candidate successful at the company (interested to learn how you do it).
