The whole process took 1.5 weeks. I met with a recruiter at a job fair, interviewed with her the following day, and then interviewed with a manager two days later. I received my offer four days later. The questions were very straightforward - Oracle seems to be using the schools they recruit at as their screen, so they stick to behavioral questions. Be ready for why Oracle, why sales, and standard behavioral questions. They are, however, very disorganized in the hiring process (i.e. I received a "second" offer two days after the first) - their system has some bugs. Try to talk to the recruiters to be sure you're both on the same page.
