I applied through a recruiter. The process took 1+ week. I interviewed at Visa Inc. (Ashburn, VA) in Mar 2012
Interview
The recruiter called me, then I had a phone interview with an engineer, then one in person with the hiring manager and his boss. That was it. I didn't have any technical questions as part of the interview. I think somehow the hiring manager trusted my initial statements, and did't feel the need to go deep into any technical details.

Question 1
They asked about the experience in enterprise networks, and in troubleshooting calls.
