It's important to do your research before an interview. This question can be easily answered if you take the time to learn more about the organization and role beforehand. The interviewer wants to be reassured that you're not just looking for any job. What about the position stands out to you? If you are currently in the role at another company, talk about how this position is different and fulfills something that you are missing from your current job, or better yet, how this role will help you accomplish your goals.
