I applied online. The process took 1+ week. I interviewed at Oracle (New Delhi) in Aug 2020
Interview
2 rounds of technical discussions which was mostly scenarios based and my analysis about future technology and trends, I will suggest don't put anything in CV which you haven't work on and be honest this goes for all companies.
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
