Frontend interviews in 2026 typically have 4-5 rounds: a phone screen with JavaScript/CSS questions, a coding challenge (build a component or solve an algorithm), a system design round (design a chat app frontend, infinite scroll), a React/framework deep-dive, and a behavioral round. Companies like Google, Meta, and Amazon focus heavily on JavaScript fundamentals and data structures, while startups emphasize practical React skills and system design trade-offs. Preparation should cover all these areas with emphasis on your weakest spots.
Week 1-2: JavaScript deep-dive — closures, prototypes, event loop, promises, and common gotchas. Week 3: CSS mastery — Flexbox, Grid, specificity, responsive design challenges. Week 4: React patterns — hooks, component design, state management, performance optimization. Week 5: System design — component architecture, state management at scale, API design, caching. Week 6: Data structures & algorithms — arrays, strings, trees, and common LeetCode patterns. Throughout: practice behavioral questions using the STAR method with your real experiences.
Generic interview guides waste your time on topics you already know. If you're strong in React but weak in algorithms, your prep plan should reflect that. Free Class AI creates a personalized study plan based on your experience level and the type of roles you're targeting — FAANG, startups, or mid-size companies. Each has different emphasis areas and question styles.
