Hire TypeScript Developers Who Know the Type System
TypeScript fluency is more than `let x: number`. Assess candidates on generics, conditional types, narrowing, and real TSX — with live type-checking and integrity detection.
Full compiler in-browser
Type-checked
Code coherence detection
To first live interview
Everything you need to hire typescript engineers
Live type-checking, generic-friendly questions, and integrity detection built for TS hiring.
TypeScript 5.x in Monaco
Full TS compiler running live in the editor — candidates see type errors as they type, just like VS Code.
Advanced type MCQs
Curated questions on generics, conditional types, mapped types, narrowing, variance, and type-level algorithms.
Live TS execution
Candidates compile and run TS inside the assessment. Errors surface inline, not after a long CI run.
AI code review
Claude-powered analysis of type design, narrowing choices, and API ergonomics.
Pair-programming interviews
LiveKit video + collaborative TS editor for live type-design sessions.
AI-proof integrity
Code coherence AI flags ChatGPT-generated TS; keystroke biometrics catch takeovers.
TypeScript templates
Frontend, backend, and library-author TS templates calibrated for different seniorities.
Time analytics
Measure time-per-question to calibrate difficulty.
Built-in pipeline
Job posts, kanban pipelines, structured feedback, PDF reports.
Built for TypeScript hiring, end to end
Skill signal, integrity, and pipeline — all in one platform.
Test type design, not just syntax
Great TS hires think about types as a design space — when to narrow, when to generic, when to stop. ClarityHire lets you pose real type-design problems with a live compiler in the editor.
- TS 5.x compiler in-browser with IntelliSense
- TSX + JSX fully type-checked
- Type-only questions supported (no runtime needed)
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
Post the role
Use a ready-made template or build from scratch. Embed the posting on your branded careers page in minutes.
Invite candidates
Send assessments by email or CSV bulk import. Each candidate gets a unique, revocable token-protected link.
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 TypeScript topics can I assess?+
Generics, conditional types, mapped types, template literal types, narrowing, variance, distributive conditional types, branded types, plus applied work: React TSX, Zod, tRPC, and library authoring patterns.
Do type-only questions work without running code?+
Yes. You can write type-level problems where the answer is a type signature or a utility type. The TS compiler validates candidate answers via type-level assertions.
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.
