Meta Frontend Engineer Interview Questions

I would minimize sensitive data in the browser, avoid unnecessary persistence, and be careful about what appears in logs, analytics, and shared UI states. Privacy is partly a product decision, so the frontend should support data minimization by default.

I would reduce the number of decisions the user has to make early, surface value quickly, and use progressive disclosure instead of overwhelming them with options. Good onboarding should move the user toward a meaningful first success as fast as possible.

It looks like shared expectations on contracts, timelines, and failure modes instead of last-minute integration surprises. I would want the frontend to own user experience, the backend to provide reliable APIs, and design to guide consistency and clarity.

I would weigh maintenance pain, bug rate, velocity impact, and user risk. If the code is blocking product work or causing repeated incidents, the refactor is usually justified, but I would still prefer incremental change over a risky rewrite.

I would connect my answer to building high-scale, highly interactive products where performance, UX, and reliability all matter. A strong answer should show that I am motivated by the complexity of products used by a massive audience and the need to make them fast and intuitive.
