A few jobs back we did something similar, and posted in the ad that people could apply by solving http://unhelpfulclue.aqxs.net/lookup.php (Resulting email changed)

Technical tests before screening appear to be getting more common. Currently job-seeking, I'm getting a little frustrated by the number of times I have to prove that I can actually implement variants of Fizz Buzz. It'd be nice if I could submit a link to a previously completed Codility test or something...

(Yeah, it'd be nice if they accepted Github links or something as proof of technical competence, but as someone on the other side I don't really want to have to validate a hundred random OSS projects and check the province of the code in them)
