You know what's super weird?
My company selects for people who can pass white board interviews. Which are not only terrible in their own right but also not the way anybody I know codes.
And despite that, most of the people I work with are actually below average at explaining things with drawings or whiteboards. And since that average in our industry is already "pretty awful" that's saying something.
So not only are we looking for the wrong thing, but we haven't even proven our own people can do the thing we thought we were looking at. I'm starting to think a lottery system would be better. We know we have algorithms that do better with random sampling. Maybe hiring is one of them.
