I applied through a recruiter. The process took 1 week. I interviewed at AT&T (San Diego, CA) in Jun 2012
Interview
Contacted by third party recruiter. Interview process was handled by the company that I would be a subcontractor for if I was hired (HP Enterprise Services in this case).
Interview questions [1]
Question 1
The network architects asked a myriad of questions but none were too difficult. Some questions were more "interesting things to know" rather than practical knowledge needed for the job
