Answer
Connect what you actually know about the company with what you want to do and how you can help.
How to structure the answer: Refer to the product, users' problems, the scope of responsibility or the way of working. Prepare a question of your own that checks whether your picture of the role is accurate.
Practical note: Avoid generalities that would fit any company. Don't claim to know a team's culture you haven't had a chance to see yet.
This is a structure for preparing your own answer, not a ready-made story about your experience.
