Expedia Group Software Engineer interview questions & guide 2026

Interview questions at Expedia Group test your foundational understanding of computer science, real-world software design capabilities, and behavioral fit with company culture. While exact questions vary by team and seniority level, evaluations consistently focus on practical problem-solving and clean execution rather than trick algorithms.

Data Structures & Algorithms

This category tests your ability to select efficient data structures, write clean code, and analyze time and space complexity under real-time constraints.

• Given a string, rearrange the characters so that no two adjacent characters are identical.
• Group an array of strings into anagrams using an efficient HashMap approach.

Preparing for an engineering interview at Expedia Group requires a balanced focus across technical fundamentals, architectural thinking, and behavioral readiness. Your interviewers evaluate not just the final output of your code, but how structured, clear, and adaptable your thought process is when navigating ambiguity.

Technical & Algorithmic Execution – Interviewers expect you to quickly translate verbal requirements into clean, idiomatic code. You must demonstrate strong proficiency with standard data structures like HashMaps, Trees, Heaps, and Graphs, explaining time and space complexity ($O(N)$ notation) clearly as you develop your solution.

System & Architectural Scalability – For backend, full-stack, and senior roles, you will be evaluated on your capacity to build distributed systems. Demonstrating awareness of microservices architecture, trade-offs between SQL and NoSQL databases, caching strategies, rate limiting, and idempotency will set your response apart.

Expedia Core Values & Behavioral Fit – Expedia Group places significant weight on cultural alignment. You should articulate past experiences using the STAR method (Situation, Task, Action, Result) while explicitly demonstrating ownership, inclusive collaboration, and a bias for customer-centric action.

Communication & Collaborative Problem-Solving – Treat your interview as a collaborative working session. Interviewers want to see how you respond to feedback, handle changing constraints, and explain technical trade-offs to team members.

The hiring process for a Software Engineer at Expedia Group moves through a structured pipeline designed to evaluate both technical mastery and personal work style. The journey generally spans three to four weeks from initial application to final decision, though timeline pacing depends on role level and regional location.

The process opens with an online technical and personality screening, designed to verify core problem-solving speed, fundamental computer science concepts, and cultural preferences. Candidates who perform well transition to a recruiter or hiring manager screening call, which confirms team alignment, background details, and compensation expectations.

The final stage—often conducted as a virtual super day or loop—consists of consecutive technical and behavioral rounds. These live sessions focus on live data structure coding, system design architecture, and behavioral deep dives into your past engineering projects.

The visual timeline above illustrates the standard sequence from initial assessment through technical loops to the final hiring offer. Candidates should pace their preparation accordingly, focusing first on core algorithms and language fluency before moving into live architectural whiteboard practice and behavioral story framing.

To excel during your technical loops at Expedia Group, you must understand the specific technical competencies evaluated across each stage.

Data Structures & Algorithmic Coding

Algorithmic interviews assess your ability to break down complex problems, select optimal data structures, and write bug-free code live on a shared environment (such as HackerRank or Zoom).
