Skyscanner's Interview Process (2026)

Blog / Skyscanner's Interview Process (2026)

Skyscanner's software engineer interview process typically unfolds across 4 to 6 stages, with the exact structure varying depending on your seniority and the team you're applying to. Most candidates report a clear split between an early-careers track centered on a Discovery Day and an experienced-hire loop focused on system design and project depth.

Recruiter Screen: Usually a 30-minute call covering your background, interest in Skyscanner, and practical logistics like salary expectations and notice period. It's fairly standard and sets the tone for the process ahead.
Online Technical Assessment: Early-careers candidates typically complete a coding test on a platform like HackerRank, often featuring problems inspired by real Skyscanner challenges such as flight data processing. Experienced hires more commonly receive a take-home recruitment task, such as building a flight results page, or a live coding session, usually with around 7 days to complete it.
Discovery Day (Early Careers): A half or full-day event, either virtual or in-person, that serves as the final stage for graduate and early-careers candidates. It generally includes a group exercise, a one-on-one technical interview, and a culture conversation assessing values alignment.
Final Interview Loop (Experienced Hires): Mid-level and senior candidates typically go through a multi-round loop covering system design, a deep dive into a past complex project, and a structured values and leadership fit interview. The system design round usually runs around 60 minutes.

To make the most of your prep time, focus on the three core areas that Skyscanner consistently tests across its engineering interviews:

Data Structures & Algorithms (DSA): Coding challenges inspired by real Skyscanner problems, covering trees, graphs, and log parsing at scale.
System Design: High-level architecture questions focused on scalability, trade-offs, and end-to-end ownership of services.
Take-Home Project: A practical coding task, often a front-end or full-stack build, typically given to experienced hire candidates.
Behavioral & Values: Structured behavioral interviews assessing cultural alignment, ownership mindset, and how you work with others.

1. Data Structures & Algorithms (DSA)Skyscanner's coding questions tend to be practical and grounded in real product scenarios rather than purely abstract puzzles. Recent candidates report questions like finding the maximum depth of an N-ary tree, which you can practice with Binary Tree Level Order Traversal and related trees problems.Log parsing at scale is another theme that surfaces, where the challenge is not just parsing but making data searchable efficiently. Problems like Match Logs to Queries and Implement Trie (Prefix Tree) are highly relevant here.For broader coverage, working through our top 100 DSA questions is a solid way to make sure you're not caught off guard. Skyscanner's difficulty tends to sit at the medium to hard range, so prioritize depth over breadth in your preparation.

2. System DesignSystem design is a significant focus for mid-level and senior candidates, with rounds typically lasting around 60 minutes. Interviewers are less interested in a textbook-perfect diagram and more focused on how you reason through trade-offs and take ownership of the full service lifecycle, including CI/CD and monitoring.Recent questions include designing a recurring billing platform, architecting a real-time analytics system for flight search trends, and designing a rate limiter for an internal network. You can explore the Rate Limiter solution directly, and brush up on broader concepts with our High-Level Design topic page.Consistent hashing also came up as a specific concept question, so make sure you can explain both the theory and a practical implementation. Practicing on our System Design Whiteboard is a great way to build the habit of structuring your answers visually under time pressure.

3. Take-Home ProjectExperienced hire candidates often receive a take-home task rather than an immediate live coding round. A common format is building a flight results page, fetching data from a JSON source and rendering it in a mobile-first layout around 480px wide, with roughly 7 days to complete it.Skyscanner uses React and their own open-source design system called Backpack, so familiarity with React fundamentals will give you a real advantage. Mentioning accessibility considerations in your submission, something Backpack is built around, is a detail that candidates say resonates well with reviewers.For general take-home practice and to get a feel for what polished submissions look like, check out our take-home project practice resources.

4. Behavioral & ValuesSkyscanner treats its values interview as a structured assessment, not a casual chat. Interviewers are specifically evaluating whether you act as an owner, and they pay close attention to how you handled situations involving vague requirements, difficult feedback, or conflicting opinions within a team.The STAR format is expected here, and candidates note that interviewers specifically probe for the Result and Learning components. Make sure your answers land on what changed because of your actions, using the STAR principle as your framework for structuring each story.For the Discovery Day group exercise, the focus is on how you collaborate and include others, not just whether your technical idea is correct. Practice thinking out loud, inviting input from others, and gracefully handling disagreement. Our Behavioral Playbook has targeted guidance on exactly these scenarios.

ConclusionSkyscanner rewards candidates who are technically sharp, genuinely collaborative, and show clear ownership over their work. Use the stage breakdown above to prioritize your prep, and follow our Skyscanner Interview Roadmap for a structured, step-by-step plan that takes you from first principles to offer-ready.
