IBM did exactly that when I interviewed with them in 1998. They give you a battery of tests including: A timed test of where you have to do a lot of boring math problems like long-multiplication and division of large sums. I hate boring math, but figured I didn't want to be an accountant, so I didn't stress out over it. Another timed test where you're given character sequences, and you have to guess what comes next. That was the one all us hackers in the group of interviewees were bragging about after the test. "Oh yeah? I got through all but the last two!", that sort of thing. We were told our results were not a condition of employment (though this was during the interview process) and they would be kept in our employee profiles, but we couldn't ever find out how we did.
