As I read that, I thought of all the developers I've worked with, and as a composite character, I have worked with a rock star! I can name a developer for every characteristic.

Even the guy who wore black leather pants every single day.... I don't fault him for it, he looked good in them, but that's some commitment in the summer.

Since HR and managerial types sometimes can be prone to confuse attitude for competency, maybe they really are looking for a "rock star"?!
