Round 2: Technical interview:

• OOPs concept should be very clear, because you will be asked some questions like Inheritance, Polymorphism, Run Time Polymorphism, Abstraction, Encapsulation, etc.
• DBMS questions were also asked. like( Normalization, DDL, DML, DCL, TCL, etc)
• They asked me about concepts of java (exception handling, collections, overloading, overriding, etc.). (These questions are asked to me because I have chosen java as my preferred language, for my friends who have chosen C++ or python the questions were different).
• Data Structures ( LinkedList, Stack, Queue, Graph) questions were asked.
• They will ask you to code some simple programs.

Round 3 : HR:

• This round was very easy and some questions related to the company were asked, so it will be helpful if you know something about the company.
