I was called in for an interview pretty soon after applying. The interview was pretty quick, they mostly ask about your experience with customer service. I was offered a job at the end of the interview and they had me go back to the office to do some onboarding activities the same day. It seems like they hire a lot of people at once and then weed people out through the intense training process. They might offer you a different job than you interviewed for if you don’t have much experience.
