What Are the Key Components of a System Design Interview at Zillow?
A system design interview at Zillow typically involves designing a system, such as a real estate listing platform or a mortgage marketplace. The interviewer will assess the candidate's ability to identify key components, such as data storage, scalability, and user interface.
How Do You Design a Scalable Real Estate Listing Platform?
To design a scalable real estate listing platform, candidates should consider factors such as data storage, data retrieval, and user interface.

For example, Zillow's own listing platform handles over 100 million listings, with an average of 50 million unique visitors per month.
What Are the Key Considerations for Designing a Mortgage Marketplace?
When designing a mortgage marketplace, candidates should consider factors such as data integration, user authentication, and lead generation. A well-designed system should be able to integrate with multiple data sources, provide a secure user authentication process, and generate high-quality leads for lenders. For instance, a mortgage marketplace with 10,000 registered lenders and 1 million monthly users would require a robust system to handle lead generation and distribution.
How Do You Handle High Traffic and Large Data Volumes in a System Design?
To handle high traffic and large data volumes, candidates should consider factors such as load balancing, caching, and data partitioning.
