Capital One Project Manager interview questions

I applied online and the recruiter reached out to me. Recruiter call was more about the role, hiring process, expectations, learning more about myself, salary expectations, benefits etc. Recruiter asked to prepare 3 capital one products to prepare - capitalOne shopping, capital one mobile app, virtual card numbers. During mini case 1 hour interview, started with general introduction. Then, he asked me about the feature I would develop for capital one mobile app and how can i attract more customers to use that feature?
