Please do not say just because of the aid they are giving. That should be the last thing you say actually. Talk about how you enjoy helping others(if you actually do) this is a part that's important to the program, peer assistance, you will help others succeed along with you. It is the same question as the essay part. I said it gives me hope for a better future, makes me fulfill my dreams of becoming an engineer in the future, blesses my family in the best way, takes out that burden of college debt. If you think you can talk about the financial aid part like saying because you just need the money, without sounding completely repetitive or just WRONG( in my opinion) go ahead and do it. They also asked questions that according to your answers. In the very first question I had a personal answer and I had about 2 follow up questions about it. REVIEW REVIEW REVIEW. If you can, have maybe your guidance counselor or a teacher or someone ask you these questions. I put the difficulty level to be DIFFICULT because if you do not prepare for this interview you will mess up!
