Some are saying that it’s to have both human-readable and machine-readable data. I don’t doubt that some places do that. But others don’t.

I worked at a college HR and we asked candidates for a a bunch of stuff, including both a CV and a form.

The CV was given to whoever decided whether that person was hired or not.

The forms were given to HR, so that we could independently verify information and manually add information to the college’s records.
