The candidate should discuss why they are passionate about taking this job, and how it will help them develop as an employer in the future. While they may mention what future goals they have within the company or in their career, the most important aspect of the question is about the candidate's interest in holding the position for a long time. Interviewers do not want a candidate who hopes to put the job on their resume and leave quickly. They are looking for someone who wants to do great work and stay around for a while.
