Welcome to your interview.
The question is on your right: Inheritance in Object-Oriented Programming. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Explain the concept of inheritance in object-oriented programming. How does a child class reuse or extend a parent class, and when would you use inheritance instead of defining everything separately?
