  1. Imagine Zillow receives a massive influx of user traffic during a major housing market event, like a federal interest rate change. Describe how you would scale the backend services supporting the Zestimate feature to handle this load. What are the potential bottlenecks, and how would you address them?

    Software EngineerSystem DesignTests: Evaluates the candidate's ability to design scalable systems under high load, identify critical components, and propose solutions for performance bottlenecks.

  2. A user reports that their Zestimate for a property they are trying to sell seems consistently lower than comparable properties in their neighborhood. How would you debug this issue, starting from the user report to identifying the root cause in the Zestimate algorithm or data pipeline?

    Software EngineerDebuggingTests: Assesses problem-solving skills, logical deduction, and understanding of how to trace issues through a complex system.

  3. Zillow is considering building a new feature that allows users to virtually tour properties using advanced 3D scanning technology. Outline the core microservices you would design for this feature, considering data ingestion, rendering, user interaction, and integration with existing Zillow listings.

    Software EngineerSystem DesignTests: Tests system design capabilities, including microservice architecture, data flow, and consideration of new technologies.

  4. You are working on the Zillow Offers platform. A common bug is that sometimes the initial offer generated for a homeowner is significantly mispriced, leading to negative margins. What are the key data sources and algorithmic components you would investigate to debug and prevent this?

    Software EngineerDebuggingTests: Examines debugging skills in a business-critical context, focusing on data quality and algorithmic accuracy.

  5. Design a system to detect and flag potentially fraudulent listings on Zillow, considering fake photos, inflated prices, or non-existent properties. How would your system leverage machine learning and other data signals?

    Software EngineerSystem DesignTests: Evaluates the candidate's ability to design robust systems that incorporate machine learning for fraud detection and data integrity.

  6. Zillow's search results page displays numerous filters (price, beds, baths, square footage, etc.). How would you design the backend API and data structures to efficiently serve personalized and highly relevant search results, especially when users apply multiple complex filters?

    Software EngineerSystem DesignTests: Tests understanding of API design, data modeling, and efficient querying for complex search functionalities.
