Google for example does not hire when they think it is not beyond reasonable doubt that the hire is a good one. They rather let a good candidate pass.

This should prove that numbers speak towards the idea that bad hires are very costly. Google's policy is also not to give feedback. 50 percent of their hires had to apply more than once.

I would say large companies do not need that exceptional candidate since they have so many great ones already. Exceptional won't make a difference unless it is executive role or something like that.
