I've only been asked for this when I applied to a "digital design agency" (i.e. web development) during a moment of madness. They asked me to write a GAE based web app for something or the other. I told them (politely!) that I'd do it, if they provided me with their diversity policy, specifically with an explanation of how this sort of exercise didn't discriminate against anyone (as noted in the article.) I got a "sure, we can do that" and then never heard from them again. I didn't consider that a loss.
