They asked about databases of oracle and SQL physical space and queries. It was good and easy but one should have knowledge about databases and must be prepared properly. Also positive personality matters with open mind thinking... Also, you should be able to answer your roles and responsibilities in your previous organization. Ask me to write some queries on the whiteboard and ask a few questions related to the Dataware house. The interview should be more of discussion then an exam..! However I was happy about the interview and lthe environment later accepted the offer.
