Key considerations when designing a power board for water pumps as an EE graduate

I have recently graduated in EE and I`m in the process of getting my first job. I have been asked to provide an answer to this question for a job selection process. I am not sure how to approach the question, what specifically I should be looking for. Any insights on understanding the process for achieving the design would be much appreciated. I have been told this shouldn't be a hard question, but wi

I'm not sure what the question is asking for. It almost looks like you are expected to show how the motors should be wired with the level sensors so that they turn on/off at the right time.

If that's what the question is asking, then it becomes a logic problem. So start by writing down what sensor combinations should trigger which motors to be on. In case there are combinations that are not obvious, write down your assumptions that you use.
