In asking this question, the interviewer is trying to determine if you dislike doing a major part of your job. For example, if you're a file clerk, you obviously don't want to answer by stating that you hate to file. Like most people, you probably hate doing the routine, boring administrative tasks that everyone has to do; therefore, you might want to answer accordingly, "I don't particularly like compiling the monthly sales reports. I love the sales process, meeting and negotiating with clients, working out in the field all day. Sitting in front of a computer for a few hours each month doesn't particularly appeal to me. I know it needs to be done, and I've always done this task as required in my previous jobs, but I don't particularly like doing it."
This question should be answered positively, "I will perform all of the tasks my job requires on time and to the best of my ability regardless of whether or not I enjoy them."
