About CodeArena
Our Mission
Make technical hiring evidence-based, fair, and AI-native.
CodeArena helps teams evaluate real engineering judgment instead of memorized answers or pedigree. Every candidate now has an assistant, so the signal that matters is whether they can debug under uncertainty, catch AI mistakes, verify output, and explain decisions when the stakes are high.
Our Vision
A hiring market where strong builders are recognized for how they reason, verify, and ship.
Hiring should reward practical skill wherever it was learned. We are building the system for that market: practical, AI-native, structured, and grounded in reviewable work that humans can trust.
Our Values
Real work, not trivia
Interviews built around real engineering work: fundamentals, AI direction, critique, and verification. What candidates prove here carries over to the job.
Signal in the AI era
Every candidate has an assistant now. We measure what still separates strong engineers: judgment, verification, and the ability to direct AI rather than defer to it.
Evidence over pedigree
Candidates are judged on work they complete under clear conditions, not pedigree. Reports are evidence for human review, not automated hiring decisions.
Integrity you can trust
Reviewable focus, paste, run, submit, and replay events so every result has context a human reviewer can inspect.
How We Keep Results Useful
Consistent conditions
Candidates see the same instructions, time limits, task types, and allowed-tool rules for a given technical screen.
Visible evidence
Session replay, code history, execution results, and integrity signals make the result inspectable instead of a black box.
AI-era judgment
We test whether candidates can use AI critically: direct it, challenge it, fix it, and verify the result.
Human review
Scores and benchmarks support the hiring team. Final decisions belong to people who understand the role and context.
What We Offer
Technical Screens
Run role-specific technical screens across coding, debugging, AI Critique, and verification work.
AI Critique
The screen that measures whether candidates can catch confident-but-wrong AI code and hold their ground when it pushes back.
Verification Mode
Hand candidates AI-generated code and see who can actually find the bugs versus who blindly trusts the output.
Code Replay
Watch how a candidate approached each problem, edit by edit, with test runs and final code preserved.
Fundamentals Index
A reviewer signal for core coding ability, AI dependence, and verification skill across comparable candidate sessions.
Integrity Events, Built In
Focus changes, paste events, run history, and replay give reviewers concrete context without face, voice, or emotion scoring.
14 Languages
Assess in Python, JavaScript, TypeScript, Java, C, C++, C#, Go, Rust, Ruby, PHP, Kotlin, Swift, or SQL with full code execution.
Custom Screens
Mix coding, verification, prompting, and live validation tasks into screens tailored to each role.
Are you a developer? You can sharpen the same skills in Practice.
Why We Built This
AI changed what technical hiring needs to measure. Coding fundamentals still matter, but an algorithm-only screen no longer captures how engineers actually build with AI in the loop.
We built CodeArena to measure the full workflow: solving practical problems, directing AI toward the right solution, catching its mistakes, verifying output under conditions you can trust, and validating finalists live when the team needs deeper signal. Companies get clear evidence; candidates get a skills-first process that reflects real work.
That is the hiring loop for the AI era, and it is what we are building.
Questions? We have answers.
What is CodeArena?
CodeArena is an evidence-first technical interview and live validation platform for the AI era. Companies create coding, verification, and AI Critique screens, invite candidates by email, and review results with session replay, structured scorecards, and a Fundamentals Index signal.
How is this different from a traditional coding test?
Traditional tests over-index on producing a passing solution. CodeArena keeps the fundamentals signal, then adds judgment in the AI era: whether candidates can catch confident-but-wrong AI code, verify output, and direct an assistant well. The Fundamentals Index turns that into a comparable signal.
How do candidates join a screen?
You create a technical screen and send invite links by email. Candidates open the link in the browser, no account required. Results, including code replay and integrity events, appear in your dashboard.
Can developers use CodeArena to practice?
Yes. Developers can sharpen the same skills in Practice, working through interview-style problems across 14 languages. It is a secondary part of the product; our focus is helping companies hire.
How much does it cost?
Company plans start at $69/month for focused teams. Business and Enterprise plans add more sessions, advanced analytics, integrations, and dedicated support. See pricing or talk to sales.
