Welcome to your interview.
The question is on your right: Selenium Java OOP and Live Coding. 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.
Describe how you apply OOP concepts in Java when building Selenium test automation, and walk me through a live coding solution you would implement.
