Is there such a thing as "overqualified"? - Ask Lemmy - Fedia

Or is it just a term made up to find an easier reason to reject job applicants?

flight risk or/and asking too high of salary
What does that have to do with qualifications? If a PhD applies for a job at a fastfood joint and asks for the same wage as everybody else, that has nothing to do with qualifications.
The guy with the PhD is much more likely to get frustrated to the point that they’re either quitting early or stirring up trouble to “improve” things. Both cost money. That’s a risk most employers aren’t likely to take.
