I applied through a recruiter. The process took 1 week. I interviewed at T-Mobile (Bellevue, WA) in Feb 2014
Interview
This was actually a very fast and simple process. After the initial phone screen which lasted less than 20 minutes I was given a 1-1 interview the same week. I met with a senior engineer and a project manager which asked me questions on qa, testing, network and device troubleshooting.
