Whether it's a pristine item, or brand voice, you should not be intimidated by the growing experience. No company or agency would prefer hiring a copywriter with limited resources or a stagnant way of performing. This is applicable in different profiles. You need to evolve within your field. You need to be willing to learn something new every day. This could be in the form of new techniques in creating copies or a modern way of promoting a product. Adaptability and eagerness to grow is the key component here. HR is looking for a professional with a precise way of dealing with learning a new topic. You can say: "I attempt to accumulate as much data as possible from effective brands and missions in that field or related fields. I likewise try to concentrate on past copies from a brand to see what works and what doesn't. A new theme is crucial for learning a new way of functioning. It doesn't intimidate, but rather I gather a sense of excitement in stretching my mind." Your answer should indicate that working on a familiar theme is exciting for you but working on a theme you haven't received before excites you even more.
