Prompt-only screen
Can they solve this isolated task?
Useful, but incomplete once candidates can bring AI into the work.
- Final answer
- Some test output
- Limited reasoning trail
Test coding, debugging, AI verification, and reasoning in one evidence packet.CodeArena tests the work modern engineers actually do: write code, debug broken systems, verify AI output, explain tradeoffs, and prove reasoning live when the decision needs it.
See more than whether a final answer passes. CodeArena tests the work engineers now do with AI in the loop, then packages the evidence for human review.

CodeArena signal pack
The screen produces evidence a reviewer can inspect before deciding.
Try the move yourself
This is the skill CodeArena screens for: can an engineer tell when confident AI output is wrong before it ships? Your reviewers see who can, with evidence.
AI assistant: “Handles rounding safely and avoids floating-point drift. Ready to merge.”
The tests pass and the AI is confident. One line still ships a money bug. Click the line you would flag in review.
Reviewers see what ran, what failed, how the candidate used AI, and what deserves a live follow-up.

No face, voice, emotion, or personality signal.
Example next step: use live validation to probe the reasoning behind the AI critique.
Open sample reportHow it works
Structured screens handle the first pass. Live validation adds signal only after candidates clear reviewable work.
Pick a pack across coding, debugging, AI Critique, verification, and prompting work.
Candidates solve executable work and AI-era review tasks, not just multiple-choice trivia or puzzle drills.
See tests, replay, integrity events, rubric notes, and pending-review guards before a decision is shared.
Escalate finalists or unclear submissions into live validation without losing the structured record.
Your team gets a role-specific screen, a candidate evidence packet, and a human-reviewable scorecard with live validation when the decision needs more signal.
Executable coding and debugging prove the candidate can reason without hiding behind a generated answer.
AI Critique and prompting work show whether they can inspect, revise, and reject weak assistant output.
Tests, edge cases, runtime output, and written tradeoffs show how they decide something is actually correct.
Finalists and ambiguous cases move into the same evidence loop instead of a disconnected interview.
Hiring signal
Surface what reviewers need first: what ran, what failed, what the judge found, where live validation is needed, and what the human reviewer decided.
Senior frontend signal pack
Test results, runtime behavior, failed attempts, and final correctness from screen or live sessions.
Judges organize coding skill, problem solving, AI Critique, verification, strengths, and concerns for reviewer approval.
Move finalists into a live room when the evidence needs deeper probing or AI-era integrity review.
No face, voice, emotion, or personality scoring. AI can summarize evidence, but humans make the hiring call.
