The process took 1 day. I interviewed at T-Mobile (Augusta, GA) in Jan 2010
Interview
At first T-Mobile will do a phone screening. This is important to sound upbeat and friendly to make it in the door.
After the screening happens you are interviewed by two management types. All of the questions are based on past experience. You have to answer the questions based on what you have done and not what you would do.
Interview questions [1]
Question 1
How would you handle a customer that is using profanity?
It’s a grueling process. Do several interviews before you go in for an actual interview. It’s more like a mixer. Meet a variety of people then do a one on one.
The interview went well, but when they asked about my desired length of stay, I explained that I wanted to stay for a considerable time, but still launch or perhaps grow the company. The interviewer then went on a rant about how they thought they would only stay at this job for a short while, and their enthusiasm seemed to wane.
After completing a phone interview there was an in person interview.There were two people doing the interview one person asked the questions the other took notes. It didn't last long and they were very nice.
