As something of a counterpoint, a literal 4-hour assignment isn't that bad--especially as an alternative to a day of interviews. If they give you the assignment and it's immediately obvious that it's actually a 20+ hour assignment, you can always just walk.
When I worked for a technology analyst company, we would ask for writing samples--which most potential hires would already have. But, if someone didn't, they'd have to create one. It was very reasonably a non-negotiable requirement given that's what they'd be doing day to day.
