Hi Dragonfly
I'd assume they try to give everyone an equal opportunity. Experience that can transfer to the job matters a lot. As someone with a uni degree, they couldn't care less about it (which I was totally expecting anyway). What they want to know is if there is anything that might tie you down. There may sometimes be nights where you have to sty away from home so if you have a family that can be looked after when you're away/don't have a family that's good enough.
