Welcome to your interview.
The question is on your right: Liquid Pumping Uphill Physics. 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.
Can you describe a system to transport a liquid from one tank to another tank at a higher altitude? Several follow up questions about details in the answer and the physics involved in pumping a liquid uphill.
