Company: Stripe
Role: Product Manager
Category: Product Design & Strategy
Difficulty: medium
Interview Round: Other
Design a tax-preparation product like TurboTax that walks individuals through preparing and filing their income tax returns.
```hint Start from the shoebox
Tax situations vary enormously. Before listing features, pick a kind of filer and think about what they must gather and understand before they can answer even the first question about their return.
```
### Clarifying Questions
- Are we designing a new tax product from scratch, or improving TurboTax as it exists today?
- Which returns are in scope: US federal and state individual returns only, or business returns and other countries too?
- Is the main business goal more filers overall, more paying filers, or more filers coming back the next tax year?
- Can the design include paid access to human tax experts, or should it stay fully self-service?
### What a Strong Answer Covers
- A goal for the product and a chosen filer segment, justified by how painful and how valuable that segment's tax situation is.
- The filer's journey from collecting documents to an accepted return, with the specific pain points along it.
- Prioritized solutions, including how the product earns trust on accuracy, privacy and price.
- Success metrics with guardrails such as rejected returns, amended returns and complaints about upselling.
- The main system pieces a PM must reason about: tax rules that change every year, document import, electronic filing, and the traffic peak before the filing deadline.
### Follow-up Questions
- A filer learns after filing that the product missed a deduction they qualified for. What should the product do, and how would you measure how often it happens?
- How would you decide which features are free and which are paid without eroding trust?
- If a free government filing tool became available for simple returns, how would your strategy change?
