I applied through a recruiter. The process took 3 months. I interviewed at AT&T in May 2012
Interview
This was a slow process. IT started of with a HR screen. After 6 weeks or so, they scheduled an interview with a Director and 2 Managers. The interview was good. Director was very knowedgeable. The Managers seemed like they got the questions and answers from somewhere. It was pretty mechanical. It went well enough to get another interview albeit after a long lull.
A few weeks later I get a technical screen with two Architects. The interview was supposed to be a Senior level Architect but these folks asked nothing about Architecture. They asked detailed questions like build scripts and java code, how to write web services, bindings, etc, etc. I would best describe them as very senior level developers. It was kind of funny when one of them was very arrogant to add to this. I did not except this for a Senior level Architect role.
To add to this, I heard that this role was only posted to hire a sub contractor they liked but they had to go through the interview porcess to satisfy their governance mechanism.
