Expedia frontend — React code-review round (PR-review style)

Had an interesting frontend interview recently where the main focus wasn't writing new code, but reviewing existing code.

The interviewer shared a React component and asked me to walk through it like a real PR review. I had to identify performance issues, improper state management, missing keys, accessibility gaps, and suggest cleaner abstractions. They cared a lot about why something was wrong and how I'd improve readability, scalability, and maintainability.

No trick questions - just real-world frontend thinking. This felt more practical than typical DSA-heavy rounds. Good reminder that frontend interviews are evolving beyond just LeetCode.
