Why use the pool at all if you already have useful examples of inflow and outflow of money or another or the queue at the grocery store? Someone of age to understand flow rates of liquid would likely be able to understand money enough to be able to do the same calculations can’t get the same principles but with a functional analogy instead.
- nickff 5y agoThere are an infinite number of variations on the problem; you could also ask about a reservoir with inflows and outflows, or a water tower, or a continuous distillation process. I think the money variant is actually one of the worst, as it evokes no imagery (in an era of largely digital transactions), but I'm not sure the exact question asked really matters. If someone fights a hypothetical, they're usually being adversarial, confrontational, or just avoiding answering the question, which is useful information in an interview.
