Welcome to your interview.
The question is on your right: Verify Web Links No 404. 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 how you would write a script to verify that all links on a webpage are functional and do not return 404 errors.
