I applied through an employee referral. The process took 4 days. I interviewed at T-Mobile (Bothell, WA) in Jan 2012
Interview
Phone screen followed by the Panel interview. Interview was very informal. Most of the questions are random based on the role. There is nothing much to talk about as the interview questions are most of the time role specific. So, questions are asked from the job descriptions.
Questions were structured to test both analytical and business skills.
Interview questions [1]
Question 1
