Hire React Developers with Real Skill Signal
Stop guessing from resumes. Run real React coding assessments, live collaborative interviews, and AI-proof integrity detection so you hire React developers who can actually build.
Faster time to offer
Full editor support
Code coherence detection
To first live interview
Everything you need to hire react engineers
React-specific questions, live coding in a real Monaco editor, and integrity detection built for modern remote hiring.
React-ready Monaco editor
JSX, TSX, hooks, and Next.js all supported out of the box in the same Monaco editor that powers VS Code.
React MCQ library
Curated questions on hooks, reconciliation, state management, Suspense, performance, and accessibility.
Live component execution
Candidates run, render, and debug React components inside the assessment — no local setup required.
Pair-programming interviews
LiveKit video + collaborative editor lets you watch candidates build real components side by side.
AI copilot for interviewers
Suggests React follow-ups, evaluates answers, and surfaces resume signals in real time.
AI-proof integrity
Code coherence AI flags ChatGPT-shaped React solutions; keystroke biometrics catch takeovers.
React test templates
Frontend and full-stack React templates ready to go — customize questions, limits, and difficulty.
Time-per-component analytics
Measure how long candidates spend on each task to calibrate difficulty and spot anomalies.
Built-in pipeline
Job posts, kanban pipelines, and structured feedback — no separate ATS needed.
Built for React hiring, end to end
Skill signal, integrity, and pipeline — all in one platform.
Test React the way candidates actually work
Every coding question renders live in Monaco with full React support. Candidates build real components, write hooks, and see output — not pseudocode on a whiteboard.
- JSX/TSX syntax highlighting + IntelliSense
- Live render preview for components
- Multi-file questions for feature-sized tasks
Catch ChatGPT-generated code before you hire
LLM-generated code arrives as large clean pastes with no iterative debugging. Authentic coding shows typing rhythm, edits, and refactors. Code coherence AI plus keystroke biometrics score the session, not just the output.
- Edit pattern analysis (type → test → refactor)
- Keystroke biometrics detect takeovers mid-session
- Per-signal authenticity score on every submission
From application to offer in one platform
Post the role, invite candidates, run assessments, schedule live interviews, collect structured feedback, and export a PDF report — all without leaving ClarityHire. No stitched-together ATS, video tool, and assessment platform.
- Job boards with branded careers page
- Kanban pipelines with stage automations
- PDF hiring reports for stakeholders
From posting to offer in four steps

They build, you watch
Candidates code in a real Monaco editor with integrated execution. Integrity signals run silently in the background.
Interview + offer
Top candidates advance to a collaborative video interview. Structured feedback, PDF report, offer letter.
Frequently asked questions
What React topics can I assess?+
Anything: hooks (useState, useEffect, custom hooks), state management (Context, Redux, Zustand, TanStack Query), performance (memoization, re-render control), accessibility, testing (Jest, RTL), Next.js App Router patterns, and component architecture.
Can candidates run React code in the browser?+
Yes. Integrated execution renders React components live inside the assessment. Candidates see output, debug, and iterate like they would locally — no npm install, no setup.
How do you detect if a candidate used ChatGPT or Copilot?+
Code coherence AI analyzes the edit pattern of every session. LLM-generated code typically arrives as large clean pastes with no iterative debugging — those patterns get flagged with evidence. Keystroke biometrics catch takeovers mid-session, and paste events are logged with code-size correlation.
Can I run live pair-programming interviews?+
Yes. LiveKit-powered video plus a collaborative Monaco editor (Yjs CRDT) lets you and the candidate co-edit in real time. Recording, transcription, and structured scorecards are built in.
Do I still need a separate ATS?+
No. ClarityHire includes job boards, candidate pipelines, stage automations, bulk CSV import, and PDF reports. Most teams replace their ATS + assessment tool + interview platform with a single ClarityHire subscription.
