The motive of this question is to understand your attitude towards anything demeaning. The team wouldn't want to hire an individual who lacks a learning attitude to upgrade their skills. Positive feedback is very motivational. It makes us feel appreciated. At the same time, negative feedback is equally important too. It helps you understand the areas you lack or need to improve. It is impossible for a copywriter or any other professional person to be perfect without any flaws. We make mistakes, and we learn from them. That is the kind of attitude HR is looking for. You can say, "Negative feedback is a very salient element. My response to it is very different. I silently allow it to delve into my deeper level. After that, I analyze the same (whether it is applicable or not) while applying it practically with an effort for modification. Feedback of any sort is fundamental to one's growth. It helps me excel in my field, which I embrace with open arms."
