no question there will be cat&mouse here but even more incentive for some stanford grads to charge premium for “unbreakable quantum-proof interview experience” :)

I half-way suspected that's what you were going for (testing-as-a-service) but my point still stands: it is a web-of-trust bootstrapping problem. For example, Otherbranch[1] exists, is a startup, and is trying to handle pre-screening candidates, but they seem to have very few companies that are currently using them. One would assume if they were solving a real problem then companies would be beating down their door to get real, verified, actual people and yet.
