Yep there's 0 incentive to allow this by the actual decision makers (companies) to open themselves up to sending potentially law-suite leading footage to a 3rd party.
Completely valid point, but what if we invest so much in anonymizing the recordings, so that it is not possible to identify the companies or jobseekers involved?
This is a bad idea for so many reasons. For starters, you’re not going to be able to use any video where the interviewer is in a two-party consent state, and good luck determining where an interviewer is currently located with 100% confidence.
