Actually, for actors it does. If you go to a casting session, you should get payed for it. That's because they had a first chance to filter you out and they are not entitled to waste people's time. For the first filter, they use their CV and their reel (video of the actor showing itself).

I think that the same rules should apply for programming jobs. Just look at my resume and my publicly available code (that is linked from my resume). If you decide I am good enough to interview me, pay a reasonable hourly rate. This would stop the abusive practice of giving big problems to solve in our free time.
