NCR Corporation Software Developer interview questions

There are total 5 rounds-An online coding round where we can use only java to code and 20 MCQ after this we gone through 2 TR and MR and HR

It was my campus placement, The interview went for around 90 min, the interviewers were very polite. The questions asked were completely related to OOPS and their implementation in Java. One must be clear with every topic such as abstraction, inheritence and other OOPs concepts, since interviewer will ask to write code and explain them rather than theory, and also they may make some changes to the code and ask about the outputs , and then followed by a couple of coding questions based on array and string which were moderate level. questions on projects and some basic sql.
