I only had one company (D. E. Shaw & Co.) ask for my SAT scores. I was late-20s and had to have the recruiter repeat herself two more times before I understood what she was asking.

It was also the single highest density of talent I’ve ever worked, by a long shot. Crazy talented coworkers.

I would think it an inappropriate question if you're asking a PhD (or MS). You could just ask for a copy of the paper(s) or the dissertation/thesis. Some people improve over the time in the uni environment. Some people don't test well when they're bored, etc. Some just grow up.
