Five technical and one managerial round occurred.

In the interview, questions mostly related to database core internals and architecture were asked, with a lot of "why?" questions. One Python coding round happened on HackerRank (though it was basic level).

All interviews were completed within 15 days, but the recruiter took around one month to initiate the final discussion on the offer.

1. Questions on database components like SGA, PGA, background processes, undo, and redo, and their internals.

2. RAC architecture and how it works.

3. PostgreSQL concepts and its internals.

4. Some basic questions on Python scripting.
