The interviewer asks this question for two reasons. They want to see if you have professional goals and a plan to achieve them. Setting goals to improve and grow professionally shows you are motivated and dedicated to your profession. Even if your goals include furthering your education and advancing your knowledge, the interviewer wants to see that your plans include working for the agency. Companies invest a lot of money and time in hiring and training employees, and the interviewer wants to know that you will be a long-term employee if hired. Share your career goals for the next five years while ensuring the interviewer you plan to grow within the company you are interviewing with.
