I applied in-person. The process took 2 days. I interviewed at Vaco (San Bruno, CA) in Mar 2015
Interview
One phone interview with the recruiter (vaco) to talk better about the position and if I was suitable for it and after accepted, they called me again to schedule an on site interview with Googlers. They sent me a test and asked me to finished as soon as possible so they could discuss the date of my interview. The test was long, but necessary.
