The interviewer wants to know that, if hired, you will see this as a long-term position. Interviewing, hiring, and onboarding is an expensive and time-consuming endeavor for any company. Take this opportunity to discuss your career plans and goals and explain how those fit with what this company is offering. Describe your passion for this career, how you hope to make a difference, and what you like about the company for which you are applying. Research the company's vision and mission statement and understand the company culture, learning/leadership training opportunities, and other employee programs, such as community outreach and volunteer programs. Then, find ways to align this with your goals and values.
