The absolute worst case for AI that I've come across is the attempt to use AI to ask job candidates questions to extract more information from them before the company has to lift a finger. It's breaking the contract that there is a respectful connection between the company and the one who is applying. Effectively, the contract is broken when the company expects the applicant to apply with never receiving any real valuable interaction, with the ability to simply click a button to reject their time investment. This is something that needs to be regulated and banned immediately. It is the worst professional use case for AI that I've experienced thus far.
