I would love to have some input into who my company hires. The biggest thing to me is you have to be willing to learn. By that I mean don't be stuck with old habbits, know you know nothing (this might not be true), and work VERY hard. We hired a guy a few years ago that worked with me for three day and quit and then we hired another that quit after two days. How can you know wether you like the job in that time frame (I suppose they might not have liked me, but I'm just too charming). Installers do alot of crappy work before they get to do the fun stuff. I don't know too many people who would crawl face down in an attic for the fun of it.

One more thing, DO NOT curse in peoples' homes. Nothing says class like an owner walking in the room just as you drop the F-bomb.
