This just doesn't work. Lots of people can bullshit very convincingly, and even if they can't produce novel solutions, can very well explain them in a matter that makes you think they for-sure know how to do it.

Hell, I can probably still prove lots of interesting things about set theory in math, as can many other people who studied math - doesn't make me the equivalent of the world-class mathematicians who actually came up with the proof.

Empirically, "talk to someone about what they did" doesn't give me hires that actually know what they're doing.
