One of the companies I applied at recently required candidates to write a CRUD app from scratch. It was just 1 page, and really simple, but had to be done within 48 hours of receiving it. (Which obviously gives lots of time to still have a life and a job.) They also had a puzzle that you didn't have to code for, but had to tell HOW you could code for it. I think it took more time than you should ask of an applicant (they sure can't apply very many places!) but it definitely weeds out the unqualified. (And possibly the qualified that won't jump through hoops to work for average wages.)
