[thelist] Good "tests" for prospective employees?

Has anyone had potential low-end developers (html/css/light db and
scripting) complete any kind of qualifying "test" as part of the hiring
process?  I've got people interviewing for a production position next
week, and wondered if anyone had done this.  I'd like to test their css
skills, and just make sure they have experience working with site on a
real-world (rather than a textbook) basis.
