Then he asked questions related to OOP concepts, DBMS, and implementation details about my project. He discussed database connection in MongoDB. What are the drivers? What is URI?
He then asked to code me any sorting algorithm and asked questions about its working and time complexity. He asked me questions related to Java database connection which I couldn’t answer.
