I'm probably not the best person to gauge that in general, but I think the "inherent" part is where we differ.
Going back to whiteboarding: I don't like whiteboarding myself, but to be fair it does measure certain dimensions quickness-on-feet, memorization abilities, ability to exude presence, fluency in language, etc. While these are laudable abilities on their own, I agree they might not correlate with overall on-the-job performance (but it depends on the job).
I guess "job performance" is this amorphous latent variable y that is correlated with a bunch of direct predictors x which we can measure, u which we can't measure, so we use proxy variables z to stand-in for them: y = f(x, u, z).
The worry is that some candidates, who may be bad for the job, but just happen to be good at these proxy dimensions (or train for them) might get the job; on the flip side, we may exclude certain candidates who are potentially good for the job but perform badly at the proxy dimensions. Whiteboarding measures the proxy dimension z.
Edit: oh look, an article on HN's front page on this very issue:
