I applied online, received a with a day or two call and did a phone interview on the spot and after the phone interview they immediately let you know of the next phase for a f2f interview. For f2f interview I was interviewed by two managers.

There is online testing that must be completed before a phone interview is scheduled. Once they have a chance to review your tests, and if you completed them to their satisfaction, they will email you back or call you to schedule a phone interview. That interview took about 15 minutes. If they are satisfied, they ask to schedule an interview at the facility in Olathe, KS. That interview consists of 2 supervisors meeting with you and asking questions like "In your previous jobs, how have you dealt with a difficult customer?" That interview lasted about 30 minutes. After the interview, I got to sit with an associate who had been there for a while to get a feel of what the calls were like. I was then contacted back by phone a couple days later offering me the position and advising me of available schedules.
