Difficulty: medium
Interview Round: Onsite
You are the Product Manager for a low-code / no-code website builder for restaurants. The product helps restaurant owners create websites quickly and add plugins.
Answer the following:
1. Define the major restaurant customer segments and identify the best target segment.
2. Propose a monetization model and key cost drivers.
3. Calculate per-customer profitability given:
- $200 onboarding fee
- $20 monthly subscription fee
- $300 one-time onboarding cost
- $100 annual service upkeep
What is the 1-year and 2-year profit per customer?
4. The team wants to add a reservation or booking capability. Should you integrate with an external provider or build it in-house?
- External integration: 2 engineers for 2 months, $120,000 annual salary per engineer, $100,000 one-time onboarding cost, and $15,000 monthly vendor subscription
- Build in-house: 4 engineers for 6 months, $120,000 annual salary per engineer, and $5,000 monthly upkeep after launch
Assume a 2-year evaluation horizon and that revenue can only start after the feature ships.
5. What important factors are missing from a pure cost comparison?
6. If the external integration grows the customer base by 5% and the in-house build grows it by 3%, starting from 100,000 customers, what would you recommend?
Quick Answer: This question evaluates product management competencies including customer segmentation, monetization strategy, unit economics, and build-versus-buy trade-off analysis with quantitative cost modeling.
