I was contacted by a Hiring Manager to come to Interview. The initial interview was at a hiring fair for AT&T. These are not common. I did a traditional interview with an Area Manager. I was asked to come for a second interview to take the Manager's Test and verbal interview with a Hiring Manager. I was then asked to come in to take the Engineer's Exam.

the phone interview was basic , the in person interview was technical , the managers were very nice. The process did not take very long and the offer was made in person
