Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about how you implemented Hibernate in your project.
Cover how you configured the SessionFactory or EntityManagerFactory, mapped entities and relationships, managed sessions and transactions, and handled lazy loading.
