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
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
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.
