Phantom Interview

I still have not received a confirmation email for my phone interview tomorrow morning. I'm assuming the time I chose works, and I'll get a call tomorrow. Usually I use Glassdoor.com to look at companies; however, I can't find anything on this company, which is a little disconcerting to me. I'm still not completely sure what the place actually does or what I would be doing for them. I guess I'll find out that stuff tomorrow, as their website isn't much help. I can't really find any reviews online either, which I always look at before an interview. I can't help but feel like I am going into this blind. I don't like feeling unprepared, so we'll just have to see how this goes.
