There is a nasty little issue that is not very well communicated: cheating. There is a non-zero amount of grads from prestigious to lousy universities and boot-camps that cheated. Some cheated a little bit, some cheated the whole way. But this may be a factor in the STEM issue. Some non-zero amount of prospective hires may have the cred, but the company can identify them quickly as hacks. I'm going to go out on a long limb here and say that most grads from large research universities cheated their way through and know squat all.
