I applied through college or university. The process took 2 days. I interviewed at Visa Inc. (UCLA, CA) in Oct 2014
Interview
Talked to the recruiter at a career fair and got the interview on the spot. When I went for the interview it was pretty informal and a one on one interview. It was pretty easy and I thought I answered the questions well.
