Let the interviewer know that you give every task you are assigned the same level of effort and professionalism, whether it is a task you are excited about or not. Mention any methods you use to remain positive when working on something you do not want to do.

"Every task in HR is important, even if I don't enjoy doing it. This is why I approach every job I do, big or small, fun or tedious, with the same level of focus and effort. The fun jobs seem to go by quicker, but I try to find ways to turn the jobs I don't enjoy into a challenge or a game for myself. I might set a goal to complete several records in a certain time frame, or perhaps I'll custom sort the employees by name and tackle the letters of my name first. Of course, I make sure the methods I use don't impact the quality or efficiency of my work."
