Complaint Review: Class V Promotions

I initially applied for "CVP" on careerbuilder.com on 1/24/2011.

Soon after i received multiple calls from "Erin". She called numerous times leaving voice mails, that I decided not to return.
She kept calling and I accidentally picked up one day.

Because I had applied to multiple places, I asked what "CVP" stood for in order for me to verify that I applied there. She replied that "that's just the company's name", I asked again what it stood for and she quickly asked me if you could ask me some questions. and wanted to know if i could come the next day for an interview.

I felt EXTREMELY uncomfortable and told her that I was not sure if I would be available and she quickly pushed to see if I could come the following day.

If this was a legitimate business, I'm pretty sure the person scheduling the interview would have no problem telling me what "CVP" stood for in the first place.
