I applied online. The process took 4 weeks. I interviewed at T-Mobile (Bellevue, WA) in Mar 2015
Interview
Was contacted within 2 weeks of application. Phone interview with Sr. Recruit HR manager. Office interviewed the week after. Met with 4 sr. managers who all were very easy to talk to. HR was very responsive. Although I was liked and well qualified, I was not offered the position, and also realized they changed the job requirements.
