Yes. I refused to do an exercise because it was quite obviously from someone's todo list, was a rather large endeavor, and didn't demand any particular skill aside from trying to find a sensible way to handle the many special cases (think parsing linux network configuration files and a pile of environment-specific behaviors). I read it and told them (a) I had no interest in a firm that behaved that way, and (b) I had no interest in a firm that didn't understand what configuration management tools were for.
