Applied online. Uploaded resume and filled out application. Took online skills test. You need 2-4 hours set aside to do this all online. Within 3 business days I received a call to set up a phone interview. 2 days later phone interview. Following week 1:1 interview at call center. Listened to calls and did a mock call where I was the CSR. That evening a request to fill out information on background came via email. I filled it out and 1 1/2 days later they offered me the job. Note: for every year of customer service you have within the prior 5 years of applying you get a higher starting pay. Emphasize that in your resume and interviews.

Applied online through the T-Mobile website. Got a call back about a week later and answered some pre-interview questions over the phone. Was invited to "A Day In the Life" where you see a presentation about the company, position, and benefits and then go sit with a rep to listen to actual calls. Was then sent an e-mail to choose my interview date. It's a behavioral interview so the questions are like "Tell me about a time when..." and they are looking for specific examples from your past work history so it's best to practice at home first. They use the S.T.A.R. method: state the SITUATION/TASK, explain what ACTIONS you took to handle it, and tell the RESULTS. After the questions, I was left alone and given 10 minutes to study a paper about a mock company (you are not required to memorize it though). Then, the interviewer called me from another room acting like an actual customer calling to cancel service and I was expected to convince her not to cancel and present her with different options more suitable. She came back in the room and asked if I had any limitations on my schedule and said they were going to run a background check which took about 7 business days to complete. Then they called me with the job offer. I start in a week!!
