This doesn't work when there are terrible devs somehow stealing paychecks from big companies for years, not even mentioning interview fraud. I've interviewed credentialed people who can't write fizzbuzz. Until tenure and credentials indicate skill, they can't be used!
Some companies I think do indicate skill, like a L5 at Google can do fizzbuzz I'm sure, but somewhere like Cisco or random small startup might as well be nowhere. As for education, no CS program in the country is a guarantee.
This is such a tired canard. Do these people exist? Yes. Assuming you can hold an in depth, detailed technical conversation with them I'd contend the percentage of these people is astonishingly low. We spend way too much mental energy defending against them.
The real problem is not enough interviewers can discuss in depth technical bits themselves, and thus they can't get signal when talking to a candidate.
