Real Estate App Teardown: Core User Problem and One Key Improvement

You are interviewing for a product manager role at DoorDash. Pick a real estate app you know well, such as one people use to search for, buy, sell or rent homes, and answer the two parts below. ### Clarifying Questions - Can the app come from any country and any part of the property market (buying, renting, commercial), or should it be one the interviewer is likely to know? - Should the improvement serve one side of the marketplace, such as buyers, renters, sellers or agents, or the business as a whole? - Are changes to how the app makes money, such as how agents or landlords pay, in scope, or only product changes? ### Part 1 — The app and the problem it solves Name the app, say who relies on it, and explain the problem it solves for them. ```hint Look at both sides Property apps usually sit between people looking for a home and the agents, landlords or lenders who serve them. Ask what each side could not easily do before the app existed. ``` #### What This Part Should Cover - The main users on each side of the app and the job each relies on it for. - What was difficult before the app (access to listings, price information) and how the app changed it. - Who pays for the app (its revenue model) and where that pulls against the problem users come to it for. ### Part 2 — How you would improve it Propose an improvement: choose the users you would focus on, the problem you would fix for them, the change you would ship first, and how you would know it worked. ```hint Go past the search results Browsing listings is usually the most polished part of these apps. Follow a serious user's journey beyond the listing page and look for the moment they leave the app or lose confidence. ``` #### What This Part Should Cover - A chosen segment and stage of the journey, with the reason for choosing them. - Pain points ranked by frequency, severity and fit with the app's strengths. - A focused first change, how it works, and what was left out on purpose. - Success metrics and guardrails for both the users and the business. ### What a Strong Answer Covers - An app the candidate actually uses, described accurately, without presenting existing features as new ideas. - A clear line from the problem named in Part 1 to the improvement proposed in Part 2. - Two-sided marketplace thinking: an improvement for consumers must not undercut listing supply, agents or revenue. - Risks specific to property: stale or fake listings, fair-housing rules, and estimates that users treat as facts. ### Follow-up Questions - Your improvement helps buyers, but agents complain that it reduces the leads they pay for. What do you do? - A home purchase can close months after the first search. How would you test your change and decide whether to keep it? - How would your answer change in a market where most listings are rentals posted by individual landlords?
