I hate this so much.

If you want to do a video interview, sure. But I'm not going to willingly give you a recording of myself without clear use terms.

How long are these files retained? Is this video subject to data privacy laws? Since they're requesting it be uploaded elsewhere, how many 3rd parties am I involving myself with by the end of this interview process?

Not to mention, we live in the era of deepfakes for voice and video. Do I have any gaurentee that this won't be used to train some AI model somewhere?

This level of hoop-jumping pre-employment should be made illegal on par with hazing laws. Not everyone can afford to be picky about potential employment.
