Silicon Valley is a bit different. There is usually a gauntlet of multi-day interviews even for the lowliest position at a startup nobody has heard of. It's even more of a gauntlet at the large, established companies. I've heard of someone doing 10 days of interviews at amazon.com, and they are a company most want to avoid. Companies are very afraid of hiring the wrong person.
As you have noted, most everywhere else the developer is made to feel lucky to work at a folding table in an unheated area next to the men's room.
