Done completely by phone when I interviewed in 2012. Spoke with a recruiter and then received email package with information and job offer upon completion of drug screen. It took a few weeks to actually begin working.

Easy and conversational. They wanted to know why I would like to work there and my customer and about what experience in customer service I had previously. The interviewer was very friendly. I had one brief phone interview and then an in person interview with my future manager.
