You apply online and take an online assessment. If you pass a recruiter will phone you and interview you for up to an hour. It is more conversational than interview like and it probably assesses how well you think and respond. If you pass that test you will be invited in one on one or at an open house for an interview with a sales manager. They mainly want to figure out if you have worked in a call center (big plus), can make outbound calls, can work without calling in and that is about it.
