Answer
Order of decorators can affect behavior. Frame the concept in practical terms so you can explain it during interview discussion.
The sequence in which decorators are applied can significantly impact the final behavior of the object. For example, in an e-commerce system, applying a discount before tax might yield a different result than the other way around. Careful consideration of the order is necessary to ensure desired outcomes, and sometimes, you might need to create custom combinations to ensure correctness.
