Yeah, just to second them, most companies won’t share much more than the vaguest of summaries of your time there. Such as “yes they worked here between these dates doing job”. Keep in mind the person answering the phone most likely doesn’t even know who you are unless you give a direct line to your direct report.

But there’s a bigger reason; they could potentially be sued for damages. If what HR has in the file isn’t true, or the manager misremembers, or any other long list of things. They would be defaming you. Hard to win, harder to prove, but still something most companies want to steer clear of.

There are also state laws which dictate what can and cannot be said about a past employee, but that varies from state to state.
