Barclays Interview Question

Tell me about yourself.?the interviewer asked about Object-Oriented Programming (OOP) concepts, such as operator overloading, the operators that cannot be overloaded, and the significance of polymorphism. The discussion then moved on to Database Management Systems (DBMS), where I was questioned about various types of keys, the concepts of 1NF, 2NF, BCNF forms, and potential issues like Dirty Read and Phantom Read.
