(LOL) Sorry, but this one always strikes me as funny in a Dilbert-esque way.
I'd seriously suggest that you go through an agency that does
screening/interviewing by another developer, preferably a highly skilled
one. Tests can be cheated on or just show trivia knowledge, not true
programming skill. The only way I've been able to effectively determine
someone's skill is by talking to them about their previous projects and
asking open ended questions about programming.
