Frontend Interview Preparation Checklist
Use this as a final pass before your interviews — tick off each area so nothing catches you off guard.
Technical checklist
JavaScript: scope/hoisting/closures, this, prototypes, event loop, promises, array methods, debounce/throttle. React: hooks, rendering & keys, state as a snapshot, immutability, memoization, common bugs. CSS: box model, Flexbox, Grid, specificity, responsive, accessibility. System design: RADIO, rendering strategies, state, APIs, caching, Core Web Vitals.
The night before
Do one revision pass with a cheatsheet, re-skim your STAR stories, research the company (product, stack, recent news), prepare 2–3 questions to ask, and sleep. Don't learn anything new the night before — consolidate what you know.
