Or is it just a term made up to find an easier reason to reject job applicants?
So it looks like the consensus is “overqualified” is a euphemism for
- “I’m afraid you’ll leave this job because I’m assuming you’ll have better chances elsewhere” aka “you won’t accept being my slave forever due to lack of opportunities”
- “I’m afraid you might actually understand how shitty it is here and want to improve things. can’t have that”
- “I don’t want to figure out how much to pay you when you know your worth”
- “You cost too much”
- “I have other reasons, but won’t say them”
Sometimes it means “We don’t want to spend a lot of money training this guy who we won’t be able to retain if he gets a better offer.”
At really entry-level jobs like fast food, where training is quick and turnover is always high, it sometimes also means "This guy might be able to read the workers’ rights poster on the door and explain the workers’ comp program to the idiot who spilled boiling grease on his foot.
