Welcome to your interview.
The question is on your right: Test Coverage Metrics. 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 measure test coverage, and what metrics do you prioritize to ensure application stability for Squarespace mobile?
