Welcome to your interview.
The question is on your right: Balancing Speed and Coverage. 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.
How do you balance the need for speed in delivery with the need for comprehensive test coverage?
