There's already a way to validate claimed qualifications - ask to see their certificate and (if you're being particularly diligent) contact the school to verify it.

Nobody in the tech industry does this though. Maybe it's possible to graduate from college with a CS degree without being able to solve fizzbuzz? So you need to check they can program despite their qualifications? IDK though.

Certificates are ~useless in tech. I've encountered way too many candidates who have a bunch of certificates but don't actually understand anything they're supposedly certified in. They just memorized enough to pass the exam.

Yes. It's astonishing how many CS grads simply don't understand programming.

sounds like the exams suck then, to be frank. No one wants to train and despite popular sentiment university is not a training center. So why isn't there some collective effort to make good exams and certifricates? Maybe ones with an active component to start (even my AP Comp Sci test required some Object Oriented coding). The big tech sort of settled on Leetcode, but clearly that doesn't required needed knowledge even within those big tech.

Honestly I think the real issue is non-technical recruiting/hr have gotten way too involved in filtering and selecting candidates, so dipshits or liars end up getting interviewed at all. When technical eng management are actively involved in looking at a candidate, I rarely see these terrible ones show up and waste time.
