It would save everyone a lot of money and cut out the middle man if all employers could just look at SAT scores and LSAT scores along with high school GPA. There would be no more need for academia as we now know it.
If high SAT scores meant that someone had learned the equivalent of a 4-year CS degree, sure, I'd be willing to consider them equivalent when hiring for a technical position. But high SAT scores just mean that you know basic, high-school-level arithmetic and reading comprehension, which is not quite the same thing.
It would be interesting to have some kind of exam showing equivalent knowledge, but I haven't seen attempts in that direction that aren't worse assessments than the degree/GPA. For example, as weird as law-school is, the bar exam is even weirder (deliberately so), and generally a terrible model to follow.
At least in undergraduate programs there is variability in what is taught, the classes you take, the quality and type of instruction. There is almost none of that in law school.
