I applied through an employee referral. The process took 2 months. I interviewed at T-Mobile (Chattanooga, TN) in May 2015
Interview
Application, assessment, video interview done over computer, in person interview, day in the life, background check, acceptance or denial. It was a long and drawn out two month process. Didn't know what was going on half the time. Finally got a response as I was ready to give up
