Difficulty: medium

Interview Round: Other

You are a product manager asked to design a website where people post questions and other people answer them, similar to Quora. Decide who the product serves, what problem it solves better than the options people already have, and what the first version should include. ```hint Win the scarce side A question-and-answer site is only as good as its answerers, yet most visitors only read. Think about which group you must attract first and why they would show up before the site is popular. ``` ### Clarifying Questions - Is this a new standalone site, or part of a large company's existing products (for example connected to web search or to workplace tools), and does it need mobile apps at launch? - Is the audience the general public, or people inside one organization asking their colleagues? - Should the site cover every topic from day one, or start with a few domains? - What does success look like in the first year: reach, engagement, answer quality or revenue? ### What a Strong Answer Covers - The distinct roles (askers, answerers, readers and moderators) and how the product attracts answerers before askers arrive in volume. - A chosen segment and a pain point that web search, existing forums and AI chatbots do not already solve well. - Core mechanics: duplicate handling, routing questions to qualified answerers, voting and ranking, credibility signals and moderation. - A prioritized first version with success metrics and answer-quality guardrails. - Risks such as cold start, spam, misinformation and incentives that reward low-effort answers. ### Follow-up Questions - Answer quality drops as the site grows. How would you detect it and what would you change? - How does the site stay useful when people can ask an AI chatbot the same question and get an instant reply? - How would you make money without letting ads or sign-up walls degrade the answers?

  • A prioritized first version with success metrics and answer-quality guardrails.
  • Risks such as cold start, spam, misinformation and incentives that reward low-effort answers.
