Monetizing Consumer FinTech Users

This problem tests your understanding of the economics of consumer FinTech and the difference between user growth and monetization. In FIG interviews, candidates are often expected to think beyond headline customer numbers and explain why a product that is easy to adopt, free to use, and popular with consumers may still have a weak path to durable earnings.

It also checks whether you can reason about revenue sources in banking and payments, including why fee income, interchange, and cross sell can be harder to scale than user acquisition. Interviewers ask this type of question to see if you understand how business models work in financial institutions, especially when customer engagement does not automatically translate into a primary banking relationship or recurring revenue.
