Welcome to your interview.
The question is on your right: POM vs Page Factory in Selenium. 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.
What is the difference between page object model (POM) and page factory in Selenium, and when would you use each?
