Forecast the revenue ramp of a newly launched banking product, from launch to maturity
Company: Capital One
Role: Product Manager
Category: Product / Decision Making
Difficulty: medium
Interview Round: Other
You are a product manager at Capital One, and the company is about to launch a new product. Design the revenue curve for that product: show how revenue should develop after launch, explain what gives the curve its shape, and state the assumptions behind it.
```hint Build the curve from drivers
Rather than sketching a shape freehand, write revenue as the number of active customers times what each one earns, then ask how each factor changes with time since launch and with time since an individual customer joined.
```
### Clarifying Questions
- Which product is it: a credit card, a deposit account, a loan or something else, or is the choice mine? Each one earns money in a different way.
- Should the curve show revenue over time since launch, or revenue as a function of price, for example when setting an annual fee?
- Is the curve about gross revenue, or revenue after rewards and credit losses, which is closer to how a lender judges a product?
- What horizon and granularity are expected: monthly through the first year, or yearly across the product's life?
### What a Strong Answer Covers
- A concrete product choice, its revenue sources, and when each source starts for a newly opened account
- A driver-based model of acquisition volume, attrition and revenue per account as accounts mature
- The phases of the curve and why it bends where it does, backed by arithmetic that adds up
- The gap between revenue and profit: acquisition cost, credit losses and the timing of break-even
- The assumptions the curve is most sensitive to, and the metrics used after launch to compare actuals with the plan
### Follow-up Questions
- Six months after launch, revenue is running well below your curve. How do you tell whether acquisition, activation or spend per account is the problem?
- How would an economic downturn change the curve, and which revenue or cost line would move first?
- Some customers of the new product would otherwise have used another Capital One card. How does that change the curve you show leadership?
Overview: A product manager interview question asking the candidate to design the revenue curve for a newly launched Capital One product. It tests building a driver-based model from acquisition, attrition and revenue per account, explaining the shape of the curve over time, and separating revenue from profit for a lending product.
