Microsoft Frontend Engineer Interview Questions

I would rely on standards-based APIs, test on the browsers and device sizes that matter, and use progressive enhancement when possible. I would also watch for input differences, viewport issues, and font or layout inconsistencies.

I look for correctness, clarity, accessibility, performance, and long-term maintainability. I also try to keep feedback actionable and focused on user impact rather than personal style preferences.

I would separate query state, results state, and filters so the UI stays predictable. I would also think about debouncing, result ranking, empty states, caching, and keyboard-friendly interactions.

I would explain the business context, what I chose to ship first, and what I intentionally deferred. A strong answer shows judgment, not just execution, and makes it clear how I protected the user experience.

I would look at the severity of the pain, the size of the surface area, and the risk of changing a stable system. If the code still works and can be improved incrementally, I would usually refactor first instead of rewriting everything.
