I applied through university. The process took 1 week. I interviewed at AT&T (Atlanta, GA) in Jun 2013
Interview
First there was a pre-screening. Few days later came the face to face interview with two interviewers. Few basic interviewing questions. Couple days later, got a call that I got the internship and a offer letter shortly after.
