I applied through a recruiter. The process took 1 day. I interviewed at Oracle in Oct 2013

Get a chance to directly contact the hiring manager and then a telephone interview. The telephone interview is a combination of technical and HR questions. Next one day onsite interview -- all are technical questions and describing past projects.
