Vector Marketing...Summer Job?

I recently heard from a friend that she was hired by a company known as Vector. Needing a job myself I went online to apply (this was a pretty rash decision I mean it was like 2 a.m. when I talked to her). After submitting my application it informed me that I needed to call as soon as possible to book time for an interview, THAT morning at 10 a.m. I received a call from a "secretary" of Vector in my home town and she pretty much raved over my application (which by no means was spectacular. I have zero work experience and am trying to save up money for college). She was pretty amicable and chatted with me about my plans for school and then went on to attempt to encourage me to book an appointment for later TODAY (remember I JUST sent in the application that night/morning at 2 a.m.). I was pretty overwhelmed as seeing as I had a late night and sent in the application as a whim I agreed to an interview time for tomorrow in the evening instead...but now i'm rethinking this whole thing. Something just doesn't feel right with this company...
