Mel, I see your DH's point, but I think that you should still apply, because, as it's been said before, you don't have to take the job, and also, even if they didn't offer you a job this time around, it would give you a reason to call them after the interview (cos I assume you'd get this far) & say how much you'd like to work for them so that it something comes up in the future you'd love to be considered. Life's all about networking, and if they've met you before & you've impressed them with your professionalism & enthusiasm, then you've already got a step up over people who they haven't met, if that makes sense. Plus it's always good practice applying for things.
