Oracle Software Developer interview questions

One call to schedule onsite days. And then just fly to SF for two-days onsite interview. I have four group to meet. They are located at HQ, Santa Clara, and Cupertino. The whole process was very smooth. HRs are very nice and the people who interviewed me are also very friendly. They didn't ask any challenging question. We talked about my background and what their group do for most of the process.

I had behavioural and technical questions. Technical questions ranged from coding on a whiteboard( which wasn't bad ) But they also asked me a lot theoretical of questions about Operating System.
