I applied through a recruiter. The process took 5 weeks. I interviewed at Oracle (Bengaluru) in Oct 2011
Interview
Interview included 3 telephonic rounds, First one was a technical round from a colleague (later). Second one was with the manager. Last one from the group director and was more of a general discussion.
2 rounds of technical - They will ask all the technical questions based on your resume. Quite difficult
1 Manager Round - They will ask technical questions and managerial questions
Interview mostly they will ask the basics but from each and every topic for Oracle DBA like configuration, architecture, RMAN, EXP/IMP, Performance Tuning, RAC, Golden Gate, Exadata and Cloud platform question etc.
There was 2 technical interview and one managerial round. L1 round was with some Java coding using stream and theoretical questions and L2 round was more about the scenario based questions
