Many lower tier jobs already do pre-filtering with silly questionaries about ethics. Its interesting but without understanding the matrixes of questions, and hard data to prove the outcomes I remain somewhat skeptical. I'd love to see a full sample test and the metrics they use to justify questions and how they correlate. I imagine its easy to root out the the truly unqualified but quickly becomes harder after that.
