InterviewLane: Ace your frontend interview

DSA & Algorithms

Pattern-first problem solving tuned for frontend interviews. Track curated by us - start here.

Lock down the language fundamentals: event loop, closures, prototypes, promises, modules, and the DOM. Then stress-test with tricky snippets.

Frontend perf is a frequent senior interview surface - Core Web Vitals, rendering pipeline, network, bundle, and runtime.

Rules of React, hooks, reconciliation, suspense, and server components. Pair docs with question banks for full coverage.

App Router, server components, caching, route handlers, and rendering strategies.

Classic Redux, Redux Toolkit, RTK Query, and where modern alternatives (Zustand, Jotai) fit.

Optional but increasingly expected. Get comfortable with generics, narrowing, and utility types.

Frame design rounds: requirements → API → data model → component tree → rendering, perf, a11y, and edge cases.

Patterns show up in design rounds and code reviews. Know singleton, observer, factory, module, and modern variants.

The components that show up over and over. Build each from scratch at least twice; the second pass is what unlocks speed.

STAR-formatted stories for ownership, conflict, ambiguity, and impact. Prepare 6–8 stories that you can remap to most prompts.

End-to-end interview playbooks, mock interviews, and curated 75-question lists.
