it's not actually policy - it's millennial stupid-fks who can't conceive of doing anything without video. And it's a back-door way to engage in racial and age discrimination. I have no problem telling HR to get bent and not taking jobs offered by imbeciles.
Funny thing, they all back down and continue the interview process over the phone. There's almost always a face-to-face step in the interview process anyway so VC is just bs. I've only had to report one org to the Equal Employment Commission for illegal acts.
