Job interviews... lacking motivation

I had an interview this morning with the Dept. of Residence at ISU for a Hall Director position.  They don't actually know if they're going to have any positions available, and my interview is 3 weeks before they are going to OPE at the beginning of March to interview a bunch of other people.  I feel like the deck is stacked against me on this one.  I am doing a practicum right now is one of the residence halls on campus, and I feel like it is going well.  That is the extent of my residence life experience, beyond living in the residence halls and university apartments all during my undergraduate career.  So, what was the first question?  Describe my residence life experience.  I don't think I fumbled, but that was not what I was prepared to ask.  Why do I *want* to work in residence life was a question I was prepared to ask.  I don't have that experience, and that's why I'm trying to get it.  I think I have a lot of transferable skills.  Beyond that, they only asked 4-5 questions total, which, if I'd known that, I would have talked more during my answers to be able to talk about the experiences I knew I wanted to talk about.  I don't feel like it was bad or that I didn't do well at all, but I also don't feel like it was awesome.  I feel pretty blah about it.  That's not a great way to feel.  

I am really excited about potentially getting the job, because I think it would be an excellent experience that I want to have, at the place I want to be, but I don't know if that is going to happen.  And now, I don't really feel like I have the motivation to keep applying and keep applying, which isn't good at the beginning of February.  I will just continue to reflect on the conversation we had during the interview and try to come up with something to take away from it.
