It is something we see especially among students completing their graduate studies, students with a master's degree or a PhD, who are often overqualified. That may be the result of universities pushing them to produce more and more research.
For instance, a master's student has to currently do as much research as a PhD student to graduate. As a result, they will be overqualified during their graduate studies.
It is no easy task to analyze this issue and there are not many studies on it. However, some studies have been conducted. We have briefly addressed the issue previously, but I am not able to give you a definite answer on it.
