Welcome to your interview.
The question is on your right: CSS Grid vs Flexbox. 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 are the differences between CSS Grid and Flexbox, and when would you choose one over the other?
