"when a candidate arrives at a company's interview, spot-check them on their understanding of a few of "their" trickier solutions."

The verification burden shouldn't be on the hiring company, it should be Kalzumeus...

Sure, but if Kalzumeus can't verify the candidate's identity while playing the game, how could they verify it afterwards? Until someone physically walks through your door, you really have no guaranteed way of knowing who you're talking to.

I don't think they'll really need to worry about these things for quite a while, though. Good problems to have, I guess.
