The interviewer wants to hear that you are not a rule breaker, and you support the rules the company has put into place. Start off by telling the interviewer that you follow all of the company rules and are supportive of the leadership decisions the company makes regarding rules. After all, there had to be some logic to their professional decision! Next, think of an outside the box rule your company had that you simply would have made a different decision about. A sound example might be that company rule that says no insulated lunch boxes/totes can be put into the fridge because it takes up too much space. You might tell the interviewer, "If I could change one decision the leadership team made regarding a rule, I would not have implemented the rule that says employees cannot put a lunch tote/lunch box in the fridge for space reasons because it makes it so much harder to find your own food in the fridge at lunch time resulting in a line at the refrigerator and less time to spend outside enjoying the sunshine." This shows the interviewer that you respect decisions even when you recognize you would make different decisions sometimes.
