The interviewer is trying to gauge the control engineer's ability to design a control system for a given process or application. This is important because the control engineer is responsible for ensuring that the process or application runs smoothly and efficiently.

Example: “There are many different ways to approach the design of a control system, and the specific method used will depend on the particular process or application being controlled. In general, however, the steps involved in designing a control system can be summarized as follows:

1. Identify the goals or objectives of the control system.

2. Identify the inputs and outputs of the system.

3. Identify the variables that need to be controlled.

4. Select the type of controller that best meets the needs of the system.

5. Design the feedback loop for the system.

6. Select the appropriate sensors and actuators for the system.

7. Design the interface between the controller and the process or application being controlled.

8. Test and calibrate the control system.”
