Zillow's Interview Process (2026)

Zillow Interview Process
The Zillow software engineer interview process typically runs four to six weeks and is known for its practical, real-world coding rounds. Most candidates report a structured loop that covers applied coding, system design, and behavioral interviews.
  • Recruiter Screen: Usually a 30-minute conversation covering your background, interest in Zillow, and compensation expectations. Recruiters often schedule a prep call before the final loop to walk you through the specific rounds you will face.
  • Technical Screen: Typically a 60-minute virtual pair-programming session or a coding problem focused on real-world logic. Candidates generally report LeetCode Medium-level questions involving arrays, string manipulation, or data filtering rather than heavy dynamic programming.
  • Greenfield Coding: One of Zillow's signature rounds, where you are given a blank slate and asked to build a small feature from scratch. Interviewers focus on code structure, naming conventions, and how you handle edge cases rather than raw algorithmic efficiency.
  • Refactoring Code: You are presented with a functional but poorly written codebase and asked to identify flaws and improve it. Interviewers are looking for clean code principles, readability, and an understanding of testability.
  • System Design: More common at the senior level, this round asks you to architect scalable systems relevant to Zillow's domain. Recent topics include real-time notification systems and geographically distributed property listing databases.
  • Behavioral: A structured conversation using the STAR format, focused on past experiences and how they align with Zillow's culture. Expect questions around technical trade-offs, cross-functional conflicts, and decisions that impacted end users.
  • Craft Deep Dive: A technical discussion tailored to your specific domain, whether that is frontend, backend, or mobile. This round tests depth of knowledge in your area of expertise rather than general coding ability.
To prepare efficiently, organize your study plan into these core areas that map directly to what Zillow tests:
  • Data Structures & Algorithms (DSA): Applied coding problems using heaps, arrays, hash maps, and sliding window patterns.
  • Greenfield & Refactoring: Practical coding rounds focused on building features from scratch and improving existing code.
  • System Design: Designing scalable, distributed systems at Zillow scale.
  • Behavioral: STAR-based questions around trade-offs, conflicts, and user impact.
1. Data Structures & Algorithms (DSA)Zillow's technical screen leans toward LeetCode Medium problems grounded in real-world logic. Candidates frequently report questions involving heaps, arrays, and hash maps, often framed around scenarios like filtering search results or finding top-K property listings.Sliding window patterns come up often, particularly for problems involving contiguous ranges or frequency counts. Practicing problems like Longest Substring Without Repeating Characters and Maximum Subarray will help you build that pattern recognition.For heap-based problems, Find Median from Data Stream and Merge k Sorted Lists are solid examples of the style Zillow favors. These problems reward clean implementation over clever tricks.Start your DSA prep with our top 100 DSA questions to cover the highest-frequency patterns efficiently. You can also practice sliding window questions specifically to target one of Zillow's most reported themes.
2. Greenfield & RefactoringThe Greenfield round asks you to build a small, self-contained feature from scratch given a problem statement. Think of examples like building a simple rate-limiter or a component to display property search results. Interviewers are evaluating your structure, naming decisions, and how thoroughly you handle edge cases.The Refactoring round flips the script: you are handed messy, working code and asked to clean it up. Focus on identifying readability problems, removing duplication, and thinking about how the code would hold up in a test suite.A 2026 trend worth noting is that some interviewers may allow or encourage AI coding assistants during these rounds. Being able to explain why a suggestion is correct or where it falls short is increasingly part of what is being evaluated.For both rounds, extensibility matters more than finding the theoretically optimal solution. Treat them like a real code review at work, not a competitive programming contest.
3. System DesignSystem design is most prominent for senior-level candidates but can appear for mid-level roles too. Zillow-specific topics in recent cycles include designing a real-time notification system for property price drops and building a geographically distributed database for listings. You can walk through a worked example with our Notification System solution.Familiarize yourself with distributed systems fundamentals like replication, consistency trade-offs, and availability patterns. Our High-Level Design topic page covers these core concepts in depth.For practicing whiteboard-style architecture problems, use our System Design AI Whiteboard to get comfortable drawing and explaining your designs. Understanding the challenges of high-volume, slow-changing data like real estate listings will also give you an edge in framing your answers.
4. BehavioralZillow applies the STAR format strictly across behavioral rounds. Questions tend to focus on trade-offs, like choosing speed over code quality, or navigating disagreements with product managers. Frame your answers around how your decisions affected the end user, since Zillow places strong value on customer impact.If you are not comfortable structuring answers under pressure, work through the STAR principle before your interview. It makes a noticeable difference in how clear and credible your answers sound.For deeper practice, the Behavioral Playbook has situation-specific guidance that maps well to the types of questions Zillow asks. Preparing three to five strong stories that you can adapt across different question angles is a practical and efficient approach.
ConclusionZillow's interview process is more practical than most, rewarding engineers who write clean, extensible code and can think through real product problems. Start with your DSA fundamentals, then spend dedicated time on the Greenfield and Refactoring patterns since those rounds are where many candidates are caught off guard. Follow the Zillow Interview Roadmap for a step-by-step plan that ties everything together.
