I don’t follow every rule in the world and don’t expect anyone else to either.
It’s a risk using AI in a job interview situation like you describe and if I thought the risk was worth the reward I might do it.
I mean maybe there’s some very small number of classified/protected data situations (not just “these are our sales numbers and are private”) where I think maybe the integrity component actually matters.
But if it’s just some random job that doesn’t like people using AI for some bogus reason, give me a break. They can make the rules as easily as people can break them.
The school thing isn’t that different except for the risk and the reward. The risk is higher the closer you are to graduation and the reward isn’t that great since colleges are so easy these days that you almost certainly don’t need to do anything against the rules to graduate.
