Pre-MVP. AlgoArena Assessments is in early pilot. We're onboarding select teams.
Join waitlistTraditional OAs measure what candidates can do alone. Modern engineering is done with AI. AlgoArena measures how they perform in that reality, with an AI Fluency Score and behavioral replay.
Every candidate gets unlimited access to the same state-of-the-art AI models (Claude, GPT, DeepSeek) for the duration of the assessment. No wallet advantage. No tool lottery. The assessment fee covers all AI usage so candidates compete on skill, not on which $20/month subscription they happen to have.
Same models, same capabilities. Candidates who can't afford Copilot Pro or Claude Max aren't penalized.
You see every prompt, every apply, every revert. Code attribution tracks exactly what came from AI vs. the candidate.
We don't measure memorization. We measure how candidates plan, prompt, verify, iterate, and ship: the skills that actually predict job performance.
Each dimension is scored independently. Learn how scoring works →
Approach before execution, plan artifacts, time-to-first-code context.
Prompt specificity, iteration depth, blind-acceptance patterns.
Runs tests, debug cycles, resilience after AI applies edits.
Time-to-solution, idle vs active, keystroke cadence.
Quality & design signals from multi-judge scoring + deliverables.
AlgoArena is built for AI-native evaluation, not anti-AI theater.
