[1]Nothing matters more to employers than seeing that you actually have a passion for building things. There are a lot of people who have got certifications up to their eyes, but don't really care too much about tech.
There is a huge difference between the person that goes home and spends their nights working on a building cookie-baking-robot, or the next big social-networking website, and somebody that goes home and watches the TV.
I'm not saying that there is anything wrong with watching TV, just that having somebody who likes doing the type of work you're hiring them to do so much that they actually do it even when they don't have to is going to go a long way towards motivating them. It also means that they, typically, are good independent learners. I imagine that this is a hugely important trait in an industry where doing things that might seem kindof insane (like running a data-store that hasn't even reached a 1.0 release yet) is considered normal.
[1]Obviously, within reason. If you've got a passion for building things, but you think that a server is somebody that brings you food at a restaurant, you might not be well suited to a system administrator position.
(Or maybe this is all just wishful thinking. I love building things, but haven't yet gotten my dream job.)
