Expedia, Inc. Software Engineer Interview Guide

We've seen Expedia lean toward candidates who can stay calm across a pretty broad mix of signals, but the recurring theme is that clean reasoning matters more than flashy tricks. Multiple candidates described the coding as LeetCode-style and mostly easy-to-medium, with problems like Valid Parenthesis, string compression, anagrams, and palindrome variants. That tells us the bar is less about obscure algorithms and more about whether you can recognize the pattern quickly, write correct code, and explain your choices without getting tangled up.

A second pattern is how often Expedia uses the interview to probe practical judgment. Our candidates report OOP questions, big-O analysis, and follow-ups on past projects alongside the coding, which suggests they care about whether you can connect implementation details to engineering tradeoffs. The system design prompts were also grounded in real product thinking — one candidate was asked to design a notification service — so the strongest responses were the ones that stayed concrete and operational rather than abstract.

We also notice that Expedia’s interviewers tend to be friendly, but not passive. Several candidates mentioned cross-questioning, extra time to work through a problem, and a structured conversation that still dug into why decisions were made. That combination points to a company that values thoughtful communication under pressure as much as raw technical ability. If a candidate can explain their reasoning clearly and defend it when challenged, they usually come across as a much stronger fit here.
