Frontend Interview Questions: React, Web Performance, and UI Depth

Frontend interview topics—from JavaScript fundamentals to system design for UI—and how to generate JD-specific practice questions.

Frontend interviews blend JavaScript/CSS fundamentals, framework depth (often React), accessibility, performance, and sometimes product sense. JDs hint which slice matters most: design systems, growth, or infra-adjacent UI.

Paste the frontend JD into Resume Buddy AI with your resume to surface missing keywords and generate interview questions aligned with that stack.

Technical areas to review

Core JS, async, DOM, rendering models, React hooks and state, CSS layout, a11y basics, bundling, and profiling. Be ready to whiteboard a component API or discuss how you improved Core Web Vitals on a real project.

Resume bullets should name frameworks and metrics you can defend in follow-ups.
