Yes, and some employers do the same, I had to take it for a position at AT&T years ago. Also a test that would test your ability to do more than one thing at a time. You'd be given a couple of pages of math word problems, and while you're doing the problems, a recorded voice comes on and starts telling you to make changes, making you skip back and forth between problems and change what's there. The weirdest was a grueling 2 day test, where they shut you alone in a small room at a desk and you're told that you are the new CEO of a company, where the previous CEO left under questionable circumstances. I loved tests.
