Certainly you hear a fair bit about Apple as a high-pressure work environment. Long hours, lots of paranoia -- though by "paranoia" I'm specifically thinking of developers, and not revealing anything Apple might be working on that isn't publicly known yet.
Well, and related things like tracking what buildings you enter by your badge, access to specific labs, etc. Stuff to make sure people don't know more than they should.
I've worked with a lot of ex-Apple folks, and know some current Apple folks socially.
