In interview , they extensively covered Object-Oriented Programming (OOPs) concepts, Database Management Systems (DBMS), JOIN operations, garbage values, and exception handling. We delved into project details, exploring Software Development Life Cycle (SDLC) methodologies. OOPs queries revolved around encapsulation, inheritance, and polymorphism. For DBMS, normalization and SQL queries were key. JOIN operations involved understanding different types and their applications. Garbage values and exception handling focused on debugging skills. Project discussions included architecture, implementation, and challenges faced. SDLC questions explored project management methodologies.
