Then he asked me which programming language I was comfortable in and I as I chose C++ the discussion started from Object Oriented Programming concepts. There was a brief discussion on Polymorphism and Encapsulation. And then he asked me to write a program to find duplicates in an array and then asked me to do a few optimizations to the code.
Then he asked me the types of joins and to design a database for courses-student- marks and write an inner join query. And then he asked me did I have a question for them and the interview was over.
