This is a common question and ice breaker in interviews. And if you don't have a good answer for it -- why are you even here? While you're researching the company and role, make a list of what excites you about both.

Do you believe in the work the company does? Explain why. Are you interested in expanding your skillset to include the enterprise-level business they conduct? Tell them that. Does the role play to your strengths? Explain which strengths and how.

Even if your interviewer doesn't ask you this question, it's a strong way to begin or end your meeting.
