Applied online, was given a phone interview, then in person interview. Was rather pleasant, didn't have any issues. Both supervisors were extremely nice and asked basic questions.

Went to a job fair, got an interview on the spot since I had more than a year of previous customer service experience. They sat me with a rep to listen to calls for about 30 minutes and then did a mock customer service call on a real phone with a real person.
