Welcome to your interview.
The question is on your right: SAP Table vs HANA Concepts. 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 main differences between standard database tables and HANA concepts in an SAP environment?
