Frontend Interview Prep

Calibrate to the job they named. Generic leetcode dumps waste a week.

When to Use

  • Upcoming frontend interview
  • They pasted a JD and asked what to study

Tracks (pick from the JD)

JS (always): closures, this, event loop, promises, debounce/throttle from scratch, memoize, == traps, Array.sort default.

React (default): reconciliation/keys, useEffect deps, memo/callback when not to, context vs Zustand/Redux, RSC/client boundary, custom hooks extract logic not JSX.

System design (mid+): news feed, component library, autocomplete, image gallery, realtime dashboard. Always: perf budget, a11y, empty/loading/error, offline.

Live coding: debounced search, useDebounce / useLocalStorage, flatten nest, tabs with keyboard, pub/sub, CSS center + auto-fit grid.

Take-home: README is half the grade. Loading/error/empty. TypeScript + a few tests. Match their stack. No Redux for a counter.

STAR stories they must have: a perf fix with numbers, a designer/PM disagreement, a migration, an a11y push, a time they deleted complexity.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.

Your trail

Files you open will collect here, so you can find them again.

Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.

Now do this for your own.

Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
