I applied through an employee referral. The process took 3 weeks. I interviewed at Visa Inc. (San Francisco, CA) in Feb 2017
Interview
First round 30 minute phone interview with a member of the team. Second round 30 minute phone interview with another member of the team, same level. Third round final 30 minute interview with a more senior member of the team. All asked the usual why Visa, why this team, past failures/successes, etc.
