I applied through college or university. The process took 2 weeks. I interviewed at AT&T in Oct 2015
Interview
I went through 3 interviews: A screening, technical/behavioral interview and final interview with hiring manager. The interviews were very relaxed (none of them in person). The job is technical by nature but my interview was mostly based on explaining how I would solve a solution with code, which is much easier than a whiteboard challenge. The coolest part was that I was able to demo one of my web apps I developed and show them some source code.

I applied online. The process took 3 weeks. I interviewed at AT&T (Chicago, IL) in Sep 2015
Interview
Applying as a senior in college. Applied through the AT&T careers website. Received an email from and did a phone screen with a college recruiter roughly a week after my online application. He vetted me and then sent me on to a two-part call: one with the hiring manager and one with the "tech guy" to ascertain my level of technical knowledge. A few days after the interview, received a request for my SSN for tax purposes. A few days after that, received a call from the college recruiter about my offer.
NB: I was not drug-tested, but there may have been one upon offer acceptance according to a friend (urine test).

I applied through college or university. The process took 4 weeks. I interviewed at AT&T (Saint Louis, MO) in Mar 2013
Interview
Met a recruiter at a college career fair and ended up getting an interview a few weeks later.
The interview was a few really simple technical questions., mostly behavior questions.
It was pretty relaxed. Most of my interviewers weren't technical, which was disappointing to not hear about the work from someone actually performing the work.
