The frontend coding round decoded — the anatomy of a strong UI build answer (clarify, build behavior, handle loading/empty/error, add accessibility, narrate throughout), then three worked React builds interviewers love: a debounced accessible autocomplete with request cancellation, a keyboard-navigable tabs component following the ARIA pattern, and a sortable/filterable/paginated data table. With the edge cases and a11y that separate a pass from a strong pass.
A pattern-first cheatsheet for the algorithms round — two pointers, sliding window, hashing, binary search, BFS, DFS and backtracking, monotonic stack, top-K with a heap, intervals, and 1D dynamic programming. For each: the tell that signals it, a reusable JavaScript template, representative problems, and the complexity — so you recognize the pattern instead of memorizing hundreds of problems.
How to prepare for and win the behavioral interview — the STAR framework (Situation, Task, Action, Result) done properly, how to build a reusable bank of 8–12 stories that flex across any question, how to own the 'I' and end on the lesson, mapping stories to company values, and question-type playbooks for failure, conflict, ambiguity, leadership, and more — with the delivery rules and common mistakes that decide the round.
A round-by-round map of Airbnb's front end engineering loop — recruiter screen, online assessment, UI coding, frontend system design, code review, and behavioral — with what each round actually tests, how to prepare, the focus topics, and the common mistakes. Coding is one round of six; this shows you where the other five points go and how to weight your prep across a 4–6 week runway.
A practical introduction to frontend system design for interviews and real work — a repeatable framework (requirements, high-level architecture, data model, API and data flow, deep dives, trade-offs), the core areas you're expected to reason about (rendering strategy, component and state architecture, data fetching and caching, performance, accessibility, real-time), and a worked example designing an autocomplete search — with common mistakes and exercises.
A curated bank of frontend interview questions with strong, concise answers — JavaScript and the language, HTML/CSS and accessibility, the browser and the network, performance and Core Web Vitals, React (hooks, rendering, state), Next.js (Server Components, rendering, caching), and behavioral/design questions — each with a 'Show answer' you can self-test against, plus how to approach the interview itself.
A practical drill of the JavaScript coding problems interviewers actually ask — reversing arrays and strings, implementing call/apply/bind, debounce and throttle, deep clone, memoize and curry, flatten, a Promise.all polyfill, and more. Every problem comes with how to think about it and a solution, plus the output-prediction gotchas interviewers love.
