Employers who require college degrees don’t do it because they necessarily think that those with college degrees are more likely to be valuable employees. Instead, this hiring practice is a relic of the pre-Internet era. It’s an HR-move that helps companies sort out applications that are more or less likely to be worth looking at. If you were hiring in 1990, when college graduates were much fewer and when there was really no other way to verify a candidate’s basic abilities like writing and showing up to work, a degree might have told you much more.
