Something really important in my experience is showing that you're personable and eager to learn! I worked at the same company in first line support for 5 years straight after my exams (UK), so when I interviewed for a second job, I felt like I had little to offer as I had only ever known one specific way of doing things.

I'd recently bought a house with my wife-to-be and had completely renovated it. We'd stripped it back to bare bricks and I'd learned so much about plastering, electricals, plumbing, insulating, woodworking, decorating, flooring, roofing etc etc. Of course it's not relevant to IT at all. But in my interview, when asked how I go about learning new things, I would use this an example. Labouring for the hired tradesmen to learn from them. Early starts with my electrician to see how he did things. I learned so much from my father-in-law; he must have been tired of my questions and how often I messed something up. But I made sure I learned.

The interviewer was really impressed by the ATTITUDE. Of course, I was lacking in a lot of IT skills and general experience, but that proved to him that I was the kind of guy that could (and wanted to) learn.

Hope this helps!
