Welcome to your interview.
The question is on your right: OOP Concepts and Abstraction. 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.
Can you explain the core concepts of OOPS and how you apply Abstraction in your code?
