I would go for the interview pratice alone. I used to interview A LOT of candidates in my previous job and it is a skill that most could use some practice with.

I would check it out, first impressions can be wrong sometimes. You may like her and the staff the second time around. Also, im just guessing that maybe the field you want to have a career in is childcare or being a personal assistant of some sort. Experience and making contacts can only help not hurt you!

Thanks for all the great advice, girls! I ended up alling and thanking them for the opportunity, but I wanted to focus on school as I didn't realize the hours were more demanding than I had anticipated. The lady sounded sad on the phone and encouraged me to call back around summertime, as they'll be hiring again for the longer days. So I guess that's good...I can focus now on school and try there later on...with no bridges burned!
