Kayak's Interview Process (2026)

Blog / Kayak's Interview Process (2026)
Kayak Interview Process
The Kayak software engineer interview process generally follows four stages, though the exact format and focus can vary by team and role. Most candidates report a process that spans around three to five weeks from first contact to offer.
  • Recruiter Screen: A short video call, typically around 20 to 30 minutes, covering your background, interest in Kayak, and salary expectations. Expect the classic 'Why Kayak?' question, so having a genuine answer ready goes a long way.
  • Hiring Manager Interview: A 1:1 video call, usually around 30 to 45 minutes, focused on your past projects, architectural decisions, and how you handle technical debt. This is less about coding and more about showing depth of experience.
  • The Challenge: A technical assessment that varies by team. Some candidates receive a take-home project to complete over a few days, while others do a live 60-minute collaborative coding session on CoderPad. Either way, communicating your thought process is just as important as the solution.
  • Team Interviews: A virtual onsite consisting of typically two to four back-to-back sessions covering system design, technical coding, and behavioral questions. Most candidates report this totaling around two to four hours of interview time.
To prepare effectively, structure your study plan around the core areas Kayak consistently tests across its software engineer interviews:
  • Data Structures & Algorithms: Practical coding problems focused on graphs, string manipulation, and Java collections.
  • System Design: Designing scalable, travel-related distributed systems like booking caches and price alert services.
  • Frontend: React, JavaScript fundamentals, and HTML/CSS optimization for UI-focused roles.
  • Behavioral: STAR-format questions tied to Kayak's core values like 'Win as One' and 'Love Numbers'.
  • Take-Home Project: A small, self-contained project such as a UI component or backend service, completed over a few days.
1. Data Structures & AlgorithmsKayak's coding questions lean toward practical problem-solving rather than obscure algorithmic puzzles. The most reported topics include graphs, string manipulation, and Java collections, so prioritize those over niche trick questions.For graphs, problems like Cheapest Flights Within K Stops are a good reflection of the travel-domain framing Kayak sometimes uses. String problems like Longest Substring Without Repeating Characters and First Unique Character in a String also come up regularly.Interval and array questions round out the picture. Merge Intervals, Two Sum, and Top K Frequent Elements are solid starting points. Work through our top 100 DSA questions to build broad coverage before zeroing in on graph traversal questions.
2. System DesignSystem design at Kayak is often framed around travel use cases, which makes preparation more focused than a generic study plan. Expect prompts like designing a flight price alert system or a hotel booking cache, both of which test your ability to think about scale, consistency, and latency.A great starting point is studying the Hotel Reservation System solution, which maps directly to the kinds of problems Kayak asks about. The Rate Limiter is another relevant pattern worth reviewing, especially for backend infrastructure discussions.Brush up on High-Level Design concepts like caching strategies, database sharding, and pub/sub messaging before your onsite. Candidates report that interviewers push on the 'Love Numbers' value here too, so be ready to talk about how you would measure system performance and set SLAs.
3. FrontendFor UI-focused roles, the technical assessment often centers on React and core JavaScript. Candidates report questions on component architecture, state management, and performance optimization, so surface-level knowledge is not enough.Brush up on React fundamentals including hooks, component lifecycle, and rendering behavior. CSS and HTML optimization questions also come up, particularly around accessibility and layout performance.If you get a take-home or live coding session, expect to build a specific UI component rather than solve an abstract puzzle. Treat it like a real PR: clean code, good naming, and a brief explanation of your design decisions.
4. BehavioralKayak's behavioral questions are tied closely to their internal values, with 'Win as One', 'Be Bold', and 'Love Numbers' being the most commonly referenced. Use STAR format to structure your answers clearly and keep them grounded in specific situations.'Love Numbers' is worth special attention. Interviewers frequently ask how you measured the success of a feature or used data to influence a decision. Have a concrete example ready that involves real metrics, not just vague outcomes.The Behavioral Playbook is a practical resource for preparing stories across each value. Aim for two to three strong stories that can flex across different question angles rather than memorizing ten separate answers.
5. Take-Home ProjectIf your team path includes a take-home, you will typically have a few days to build a small but complete project, such as a backend service endpoint or a specific UI component. The bar is code quality and communication, not complexity.Write clean, readable code as if it is going into a real codebase. Add brief comments where decisions are non-obvious and be prepared to walk through your choices in the follow-up conversation. Practice with take-home project examples to get a feel for the expected scope and format before your assessment arrives.
ConclusionKayak's process rewards candidates who communicate clearly, think in data, and treat interviewers like teammates rather than judges. Start with the areas most relevant to your role, get comfortable talking through your reasoning out loud, and follow the Kayak Interview Roadmap for a structured, step-by-step path to your offer.
