The problem is: Writing good resumes and having a lot of experience with programming is a good heuristic for "experience" and "knows how to play the game" but not meaningfully useful for "excellent at programming".
Work-sample tests measure the latter.
A worker's experience is a heuristic for programming skill, but a heuristic of a heuristic is like an average of a set of averages: Useless.
