Trace How Rewards and Payments Move Between Apple Card and Apple Cash

In a product manager interview at Apple, you are asked a technical product question: explain how Apple Card and Apple Cash work together. Describe what each product is, how money and rewards move between them, and which partners and underlying technology make those flows work. ```hint Follow one purchase Trace a single card purchase from the tap to the reward it earns, then follow that reward to everywhere it can go next. At each step, ask which company actually holds the money or carries the risk. ``` ### Clarifying Questions - Should I focus on the US, where both products are offered, or also discuss how the design would change in other countries? - Do you want the user-facing flows only, or also the banking and payment-network plumbing underneath? - Should the answer include the related features that sit between the two, such as the savings account that can receive card rewards and the family-sharing options? - Is the aim to explain the current design, or also to judge it and suggest improvements as a product manager? ### What a Strong Answer Covers - A clear distinction among Apple Pay (the way to pay in Wallet), Apple Card (a credit card) and Apple Cash (a stored-value balance), including the role of the partner banks rather than Apple as the bank. - The flows that connect the two products in each direction: card rewards credited as Daily Cash, and the cash balance used to pay the card bill, plus what the balance can then be used for and what cannot flow between them. - The underlying mechanics: device tokens and authentication in Wallet, the card network, transfers between two banks, and transfers out to a bank account. - The product reasoning for linking them, the trade-offs it creates, and edge cases such as returns, users without Apple Cash, fraud and a change of partner bank. ### Follow-up Questions - A customer returns a purchase after spending the Daily Cash it earned. How should the reward be handled, and how would you explain it in Wallet? - If Apple had to move Apple Card to a different issuing bank, which parts of the Apple Card and Apple Cash experience would be hardest to keep unchanged, and why? - Which metrics would show that the link between the two products is helping users rather than just moving money around?
