Design a product to help people find contractors.
Summary
The article presents a structured framework for designing a product to help people find trustworthy contractors, focusing on solving the core issue of trust in high-value home improvement projects. After clarifying the problem space and segmenting users, it prioritizes style-driven homeowners, as their high-budget projects attract contractors and offer strong revenue potential. The main pain point identified is ensuring quality and design alignment. Three solutions are proposed: TrustedBuild (AI-powered matching), CraftCheck (third-party quality verification), and StyleSync (collaborative mood boards). TrustedBuild is chosen as the best MVP for adoption and feasibility, with risks like contractor onboarding and homeowner reliance on referrals addressed through incentives and partnerships.
Interviewer Evaluation
The interviewer will evaluate your answer based on the following criteria.
- Motivation: Do you understand the motivation or mission behind the product?
- Audience: Do you identify user segments to target and explain your reasoning?
- Pain points: Do you identify and prioritize the most important user problems to solve?
- Solutions: Are you creative in your solutions and detail the features you will build?
- Communication: Are you structured, clear, and succinct in your delivery? Can you adapt to new information and constraints? Do you handle feedback well?
Framework
The following is a proven framework to tackle this question type.
Clarify
Begin by asking clarifying questions to ensure you fully understand the problem. Explain assumptions you want to make, for example, the launch location and others.
Motivation/Exploration
Explore the problem space to identify opportunities for new entrants in the related market. As part of this analysis, consider key market drivers, the competitive landscape, macroeconomic signals, and broader industry trends. This process will help you define and narrow the specific problem space where you aim to compete.
High-Level Goal
After identifying an opportunity to enter the market, state a high-level goal for the product in terms of the broader problem space it aims to solve. Use this goal as a guiding criterion when deciding which customer segments to target and which pain points to address.
Explain Your Design Process
Let the interviewer know what you will do next. You will identify your target audience, list their pain points, determine the most pressing problem to solve, generate ideas for solutions, and provide a recommendation.
Users
Identify all major stakeholder groups affected by the solution, including individuals, businesses, or organizations. Then, select the group most aligned with the high-level goal.
Within that group, segment users by criteria that reveal meaningful differences in needs relative to the problem space. For example, you might segment users by their motivation, urgency of need, or other relevant factors.
If the product will be two-sided (with both demand and supply sides), determine which side’s needs will drive most of the MVP features. While interfaces will be required for both, prioritize the side whose needs must be addressed first to create a viable, monetizable product.
Finally, prioritize the segment most likely to adopt the product and generate significant revenue. Consider factors that influence adoption and revenue potential, such as total addressable market (TAM) size, spending power, and, specifically for this case, the level of supply-side interest in serving the segment.
Pain Points
Identify pain points that align with the high-level goal. A common method is to map the user journey or create scenarios (e.g., when, where, what, and why does the user experience a problem?) to uncover pain points.
In this case, the problem space has been narrowed to trust-related issues in choosing contractors. Therefore, focus on pain points connected to trust. Consider what drives distrust or lack of confidence for your chosen target segment when selecting contractors.
When prioritizing pain points, frequent criteria include how painful the problem is, how many users it affects, and how often it occurs. However, since trust-related issues arise every time a contractor is chosen, frequency and reach are constant. The key difference between pain points, then, is their relative importance to the user. Prioritize the pain point that matters most to your target segment.
Frame the Pain Point as a Goal
Once you’ve prioritized a pain point, frame it as a product goal. This goal should be a clear, concise, and measurable statement that guides the solution.
Solutions
Present your solutions by first listing and naming three distinct options. For each solution, describe what it is physically (e.g., an app, platform, or hardware), what it does, and how it addresses the pain point. Then, evaluate the options and select the best one based on user impact and implementation effort.
Risks
Mention risks associated with your solution (e.g., data privacy) and how to mitigate them.
