Welcome to your interview.
The question is on your right: Normalization and 2NF vs 3NF. 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.
Describe the concept of database normalization and explain the difference between Second Normal Form (2NF) and Third Normal Form (3NF).
