Answer:
If it can be a family member, think of parent, grandparent... or whoever you feel can help you fill out these answers adequately. Who do you find inspiring or impactful? Who has guided you through major life decisions? Who would you seek out for advice later in life? Who do you admire?
If it is not a real interview (not someone you know personally and can interview), think of famous people you find inspiring and look up to? Would you like to model your life after anyone in particular?
Describe the person- what is their role in society, or in your life? Do they serve a role in your community?
What is admirable about them? How did their life turn out? Are they successful? What is the degree of their success, and in which domain?
If they are famous, what are they known for?
What do you NOT YET know about this person that you are curious about? What questions could you ask them? About their life, their profession, their experiences, people who have inspired THEM, etc?
