Zapwater Communications interview questions

I applied online and was called in for an interview 2 weeks later. They conducted the interview with two of the coordinators. It was a very comfortable setting and they didn't make me feel uncomfortable. After I left I sent a follow up email and was contacted 2 weeks later and offered the position.

After applying for an entry level position through their employment inquiry email address (which, significantly, is different from their internship email address), I was asked for an interview. Despite being under the impression I was coming in for an entry level interview, I was only informed at the place that it was for an unpaid internship. They never even let me know the decision-- and it has been over a month and a half. While this review says nothing about the office atmosphere or their quality of work, my interaction with Zapwater was frustrating.
