I know someone who tried to apply to a position at a large tech company and could not complete their initial forms; this person has a master's degree from a top-25 university, is soon to have a Ph.D., has studied at the London School of Economics... but left high school early to go straight to college. Date of high-school graduation was a mandatory field in their online form, and nobody at the company could come up with a way to bypass the use of that form (and entering false information, of course, is not permitted). This person may literally have to go back and get a GED after obtaining a Ph.D. in order to be able to fill out a job application.
