I applied online. The process took 5 days. I interviewed at T-Mobile (Chattanooga, TN) in Feb 2013
Interview
Went through whole hiring process; online application and assessment, "day in the life" orientation, and interview with supervisors in the customer service department. All of the questions were behavioral questions, none about skills, experience and other "normal" interview questions.
Interview questions [1]
Question 1
They wanted you to answer the questions in a specific way or they would not record your response.
