Really? The skills tested here seem utterly trivial... It was fun for a few minutes, but nowhere near challenging enough to make me sit up and take notice (of course, YMMV)
It is pretty trivial... that was my point. If it weren't trivial, then people would just skip it and move on. But it's cute and still sufficiently non-trivial to be a helpful filter for the person who has to sort through the tide of resumes.
