Welcome to your interview.
The question is on your right: Designing an ERD With Keys. 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.
Draw or explain an Entity Relationship Diagram (ERD) for a provided business use case, identifying primary keys, foreign keys, and table relationships.
