Applied online, was contacted immediately to schedule an interview. Interview process was simple, you answer a few basic questions, why do you want to work here, etc..., then they take you to the call floor where you "Y Jack" with another sales agent and listen in on the phone calls, getting a feel for what the job is.
After that you do the real interview, normally with 1 team lead, you'll cover the basic stuff, past job experience, in this situation stuff, along with having to sell a random item (normally just something in the room, large jug of Antibacterial Soap in my case).
After that you speak with the HR Director and go over a few other things and they give you your start date and first paycheck date, etc...
They perform background checks, often not in before the training class but they will remove you on the spot if they find something or you lied about something.
