Hire engineers who can actually code
AI-powered assessments that test what actually matters — code reading, debugging messy code, writing features, communicating changes, and making engineering tradeoffs.

How it works
Three steps to better hiring
From job description to scored results in minutes, not days.
Paste your job description
Drop in a JD or describe the role. Our AI understands seniority levels, tech stacks, and domain requirements.
AI generates a custom assessment
In seconds, get a tailored assessment across 5 dimensions — reading, writing, debugging, communication, and tradeoffs — calibrated for your exact role.
Review scored results with AI analysis
Get detailed breakdowns with scores, strengths, weaknesses, and per-question feedback — all evaluated by AI.
5 Dimensions
Test what actually matters
Most assessments only test coding. Ours tests the full range of skills that make someone effective on a real team.
Code Reading
Can they understand what existing code does? Spot subtle bugs? Reason about architecture?
Code Writing
Can they implement functions, complete partial code, and build features from a spec?
Debugging
Can they untangle messy, real-world legacy code — bad naming, deep nesting, hidden bugs — and fix it?
Communication
Can they write a clear PR description? Explain a technical change to a non-technical stakeholder?
Tradeoffs
Can they evaluate build-vs-buy, SQL-vs-NoSQL, monolith-vs-microservices — and justify their choices?
Features
Go beyond coding puzzles
Evaluate the skills that actually predict on-the-job success.
Real-World Debugging
Throw candidates into messy, poorly-structured legacy code with hidden bugs. See who can untangle the chaos — not just solve clean textbook problems.
Communication Skills
Writing code is half the job. Test whether candidates can write clear PR descriptions and explain technical changes to non-technical stakeholders.
Engineering Tradeoffs
Build vs buy. SQL vs NoSQL. Monolith vs microservices. See how candidates reason through real decisions with no single right answer.
Anti-Cheating Built In
Behavioral analysis detects AI-assisted answers, copy-paste from external sources, tab switching, and suspicious timing patterns. Every submission gets an integrity report.
Learn moreAI-Powered Scoring
Automated evaluation across all 5 dimensions. Detailed per-question feedback with strengths, weaknesses, and section-by-section breakdowns.
Any Tech Stack
React, Python, Go, Rust, Java, TypeScript — whatever your stack. Every question is tailored with real-world patterns from your specific technologies.
Integrity
Anti-cheating, built into every assessment
Candidates using ChatGPT, copying from StackOverflow, or getting help from a friend? Evaluator catches it. Every submission is analyzed for integrity so you can trust the results.
AI-Generated Answer Detection
Identifies responses that show hallmarks of LLM output, including uniform structure, hedging language, and suspiciously polished phrasing.
Copy-Paste Monitoring
Tracks when candidates paste large blocks of code from external sources instead of writing it themselves.
Timing Analysis
Flags answers completed suspiciously fast or with long idle gaps followed by instant submissions, suggesting external help.
Tab Switch Detection
Monitors when candidates leave the assessment window to look up answers, and logs every instance in the integrity report.
Keystroke & Pacing Analytics
Tracks typing speed, active vs idle time, and editing patterns to distinguish candidates who think through problems from those copying solutions.
Full Integrity Reports
Every submission includes a detailed integrity report with risk flags, so you can make informed decisions before moving candidates forward.
Integrity monitoring runs automatically on every submission. No extra setup needed.
