Counter-counter-point. An engineering interview has a non-neglible amount of randomness. Maybe you get a grumpy interviewer or a noob interview, or your brain freezes over.

When you are considering hiring a nobody, this is acceptable. You will interview multiple people, and they will interview at multiple places, so the randomness isn't that important.

But if you want to hire one specific guy as a strategic hire, suddenly the randomness may no longer be acceptable.
