Coding Assessments That Measure Real Engineering Skill
Evaluate candidates on real coding work, not trivia. Monaco-powered collaborative editor, 30+ languages, integrated execution, and AI-assisted grading so you see how engineers actually think.
Languages supported
Less manual grading
Collaboration via Yjs CRDT
To your first live assessment
Everything your technical assessment needs
Coding tests that feel like real work, with the tooling candidates actually use.
Monaco Editor with 30+ languages
The same editor that powers VS Code. Syntax highlighting, IntelliSense, and keybindings candidates already know.
Integrated code execution
Candidates run and debug their code against test cases right inside the assessment. No local setup, no excuses.
Question pooling and randomization
Draw from question pools and randomize order so no two candidates see the same test.
Per-question time limits
Cap time on each question to simulate pressure and keep assessments focused on core skill signal.
Practice questions
Warm candidates up with unscored practice rounds so you measure skill, not test anxiety.
Template library
Start from eight focus-area templates for frontend, backend, data, DevOps, and more. Customize anything.
AI-assisted grading
Automated test execution plus Claude-powered review of code quality, readability, and approach.
Time-per-question analytics
See exactly how long candidates spend on each question — calibrate difficulty and spot outliers.
Built-in integrity checks
Keystroke biometrics, code coherence AI, and paste detection run silently throughout every assessment.
Coding assessments, done right
Every detail of the candidate experience is built around measuring real skill — not memorization.
Watch candidates code in real time
Monaco Editor backed by Yjs CRDT gives you a live, millisecond-accurate view of every keystroke. Spectate, leave comments, or jump in to pair-program during interviews.
- Real-time sync with no refresh, no lag
- Full cursor and selection awareness
- Playback every session end-to-end for async review
Run the code. Grade the thinking.
Automated test cases handle correctness. AI-assisted review grades code quality, structure, and approach — so you evaluate engineers, not LeetCode speedruns.
- Automatic pass/fail on test cases
- AI rubric for readability and structure
- Manual scorecard overlay for nuanced judgment
Integrity that is actually invisible
While candidates focus on the problem, ClarityHire measures keystroke rhythm, edit patterns, paste events, and code coherence — all without browser lockdown extensions.
- Keystroke biometrics flag takeovers
- Code coherence AI catches ChatGPT-shaped answers
- Per-signal authenticity score on every submission
From zero to live assessment in four steps
Pick a template
Start from frontend, backend, data, or DevOps templates — or build your own from the question library.
Invite candidates
Send invites via email or bulk CSV. Each candidate gets a personal token-protected link.
They code, you watch
Candidates work in a real editor with real execution. Integrity signals run silently in the background.
Grade and compare
AI scores arrive automatically. Compare side-by-side, add scorecards, and make the offer.
Token-protected invites
Every candidate gets a unique, revocable link — no public test URLs.
Full session recording
Every keystroke, run, and output stored for post-hoc review and audit.
Three integrity levels
Dial cheat detection from off to strict — match the sensitivity of the role.
Frequently asked questions
What programming languages do coding assessments support?+
ClarityHire supports 30+ languages including JavaScript, TypeScript, Python, Java, Go, Rust, C, C++, C#, Ruby, PHP, Kotlin, Swift, Scala, SQL, HTML/CSS, and more — anything Monaco Editor supports with full syntax highlighting and language services.
Can candidates run their code inside the assessment?+
Yes. Every coding question has integrated execution. Candidates can run code against visible test cases, iterate, and debug without leaving the browser or setting up a local environment.
How do you prevent cheating in coding assessments?+
ClarityHire layers keystroke biometrics, code coherence AI (Claude-powered), paste detection, edit pattern analysis, tab-switch tracking, and optional face continuity — all silently, without invasive browser extensions.
Is the grading automatic or manual?+
Both. Automated test cases determine pass/fail on correctness. AI grades code quality, structure, and approach. Your team can layer manual scorecards on top for nuanced judgment.
Can I reuse coding questions across assessments?+
Yes. Save every question to your library, organize them by skill and difficulty, and draw from pools with randomization so no two candidates see the same test.
