Summary

Interviewed for a PM role at Nubank and got hit with a product sense question about improving a restaurant. Pretty classic case-style prompt but it still made me think harder than I expected.

How would you improve your favorite restaurant?

I picked a place I actually go to regularly, which helped, but I spent too long setting up context about the restaurant itself before getting to any real insight.

Suggested Approach

Treat the restaurant as a product and apply a structured product improvement framework: start by defining the goal and user segments, then identify pain points through the customer journey, prioritize using impact vs. effort, and propose specific solutions with success metrics. Show empathy for both customers and the business, and tie improvements to measurable outcomes.

Pro tip: Anchor your answer in a clear product vision and explicitly state trade-offs (e.g., speed vs. quality, cost vs. experience) to demonstrate strategic thinking. Avoid generic suggestions like 'better service'—instead, quantify the problem and expected impact.

1. Define the Goal and User Segments

Clarify what 'improve' means: is it increasing revenue, customer satisfaction, or retention? Identify key user segments (e.g., regulars, first-timers, families) and their distinct needs.

2. Map the Customer Journey and Identify Pain Points

Walk through the end-to-end experience (discovery, reservation, arrival, ordering, dining, payment, post-visit) and pinpoint friction points or unmet needs for each segment.

3. Prioritize Opportunities

Use a prioritization framework (e.g., impact vs. effort, RICE) to select the most promising improvements based on potential impact, feasibility, and alignment with business goals.

4. Propose Solutions and Metrics

Suggest concrete product or service changes (e.g., digital ordering, loyalty program, menu optimization) and define success metrics (e.g., NPS, repeat visit rate, average order value).

5. Validate and Iterate

Outline a plan to test improvements (e.g., A/B test, pilot) and iterate based on feedback, emphasizing a data-driven and customer-centric approach.

Key Points to Mention

  • Customer empathy and segmentation: tailor improvements to different user needs.
  • Data-driven decision making: use metrics to identify problems and measure success.
  • Prioritization frameworks: balance impact, effort, and strategic fit.
  • Business viability: consider cost, revenue, and operational constraints.
  • Iterative testing: start small, learn, and scale what works.
  • Competitive differentiation: how improvements create a unique value proposition.
