My interview: good or bad?

I had an interview today to work at an audio post production facility. When I sat down with the interviewer, she told me she was interested in the work I had done interning at another recording studio, but she didn’t ask me anything about it. In fact she didn’t ask me any question other than if I’m more interested in audio or video. Most of the interview was her just explaining the job for like 15-20 minutes. At the end she didn’t give me a definite date for when I should hear from her, only that they were looking to hire soon. I asked for her business card at the end and she went through the trouble to cross out the wrong email address at the bottom and write her current one down.

How do you think my interview went? I’ve had worse and still gotten the job, but I’ve never had one quite like this.
