When you answer that represents yourself, you generally need to state the best without making it seem like you are arrogant. People like straightforwardness, so when they get to express themselves in a few words, they say something like "I am confident and presentable". Obviously, you need to fulfill the HR expectations by informing real things concerning your work experience and interests. Modify your answer to the situation and highlight the interests and qualities that are appropriate for the position you're going for.
