A phenomenal candidate can leave pretty easily, too.
But when I'm taking about not being afraid to make a "no hire" call, I'm not talking about the incredibly strong candidates. They tend to shine pretty well if you don't have a hiring process that is difficult for the sake of being difficult (e.g. brain teasers and whiteboarding). When I talk about not being afraid to dismiss someone, I'm talking about the (perhaps admirable) human urge to give an underwhelming candidate another shot.
