I have hired dozens, maybe hundreds of people in corpo jobs. I can’t vouch for any other employer, but I’ve never called anybody for anything. We had tests to verify skills and the CV was mostly a tool to know what steps to cover during an interview.
I can confirm that I didn’t care about the summer you spent flipping burgers for the much more specific, entirely unrelated jobs I hired for. It mostly only let me know it was probably somebody young and relatively inexperienced padding things out.
But then, we were hiring for a very specific type of industry and… well, we weren’t assholes. I have to imagine this sort of CV micromanagement is a thing somewhere or there wouldn’t be a cottage industry around this nonsense.
I can see that for a security role… maybe. It would have been a massive waste of time and money for what we were doing, though. Plus, this was during the good old times when people weren’t being fired left and right. If anything it was hard to find people with the right qualifications that were still available. People in the field were getting hired directly out of school. If you could pass the tests, do the job and not act like a psychopath during interviews there were very few things that would have disqualified you.
I’ll also say that I’m pretty sure some of what you describe would have been illegal over here, at least for most jobs.
