It was conversational and quick - about 20 minutes. The interviewer went over the job description, reviewed my resume, and reviewed the copywriting sample I had submitted with the application process. They pretty much know if they'll be into your writing with the sample, so the interview is basically to meet with you and person and see if the role would be a good fit. There was some small talk here and there and a few basic questions. It was very comfortable and easy going.
