I interviewed for an Oracle EBS position in the Global Financial Systems group. Had 8 interviews and very interesting ones. One thing to note is - you shouldnt bluff. I have been interviewing with many companies and I have never been "cross questioned" so much for any of my answer. If I put something on my resume, I better know it well! If I said, I did something, they are most likely to ask you more probing questions around it - why did you do it or why didnt you do something else etc!
