So This was a very interactive round . There were two interviewers , one male and one female . The male interviewer was quite experienced where as female interviewer was relatively new .

Then this conversation was followed by some core concepts of JAVA like abstract classes and interfaces . Then I was asked about my projects that i mentioned in my resume , then after some healthy discussion on those projects , the interviewer started to question about DBMS , I was asked some basic queries followed by some advanced queries and then followed by a discussion on SQL vs NoSQL .
