It is a phone interview. I have spent 30 minutes talking about my own experience. The hiring manager has spent about 20 minutes talking about the job requirements. Then we asked each other some questions. Express our expectations. The process was good. The only catch was that it sounded like a dead end position to me. Therefore, I was not very interested at the end of the interview.
