I applied online. The process took 2 months. I interviewed at AT&T in Oct 2012
Interview
You have to apply online, then if you get selected, you are invited to take a skills assessment test. If you pass that test, you are invited for an interview. After the interview, you are called and asked if you want to accept the offer. Then you select the garage that you're going to work at. And they give you your orientation directions as far as the location and time.
Interview questions [1]
Question 1
I can't recall. I guess the most difficult question is "What is your definition of customer service?" Because thats such a vague question, so its best to give as best a detailed and sensible answer as possible.
