Just a one on one with manager of customer service (essentially). I've seen the GM jump in a few random interviews too. More of a chat than anything with easy questions. They ask for information about the company so study up.

The interview process consisted of 3 rounds- phone interview, in-person interview with the manager and in-person interview with GM. The phone interview was 10-15min. The in-person interview was about 30min with them asking behavioral questions. The GM interview was more of a meet and greet and to make sure that I would be a good fit.
