I applied online. The process took 2 weeks. I interviewed at AT&T (Atlanta, GA) in Feb 2013
Interview
First phone interview, then face to face interview. Face to face part was with two people. We went over my resume, I went into details about my experience and education. Then they told me about the position and asked me general interview questions like are you a self starter, can you tell us about a time when..etc.
The whole experience was professional and they were really nice towards me.
