This is not very surprising. I've always thought that it's more of correlation than causation. If you're a good problem solver, then there is a good chance that you are probably good at both college admission and software engineering. So companies have been using it as their proxy for hiring because... why not. I'm not saying college curricula are useless, but this dependency on (imperfect) correlation might have caused significant opportunity costs for talent acquisition and now companies are slowly acknowledging it.
