Two Ways to Use DynaLab

Whether you're evaluating talent or sharpening your skills — DynaLab measures what actually matters in AI-assisted engineering.

For Engineers

Level up your AI coding skills with evidence-based scoring.

Developers who verify and iterate on AI suggestions produce significantly higher quality code. Practice the skills that actually differentiate you — verification discipline, context engineering, and knowing when AI is wrong.

  • Real codebases, not algorithm puzzles
  • 7-dimension scorecard showing exactly where you stand
  • Shareable skill profiles for your portfolio
  • Free forever — no credit card, no trial period

Free forever for individuals

For Hiring Teams

Stop reviewing take-homes. Start seeing evidence.

Send an assessment link. Get a calibrated scorecard back. Automated scoring. ~$3 per assessment instead of hours of senior engineer review time.

  • See who thinks critically with AI vs. who copies suggestions
  • Automated scorecards — 80%+ less reviewer time
  • Side-by-side candidate comparison on consistent criteria
  • Session replay with timestamped evidence for every score

From $99/mo for teams. 14-day free trial included.

How DynaLab Compares

Traditional assessments miss how engineers actually work with AI. DynaLab captures the full picture — process, not just output.

Time investment

2-4 hours async, 5 min scorecard review

Take-home: 4-8 hours candidate, 1-2 hours reviewer

Whiteboard: 45-60 min live

What's measured

Full process — verification, context, recovery

Take-home: Final output only

Whiteboard: Algorithm correctness

Scoring

7 calibrated dimensions with evidence

Take-home: Subjective reviewer opinion

Whiteboard: Pass/fail

Reviewer effort

Minimal — automated scorecard, quick review

Take-home: 1-2 hours per submission

Whiteboard: Real-time attendance required

Cost per assessment

~$3 per assessment

Take-home: 1-2 hours senior engineer time per submission

Whiteboard: $150+ (platform + interviewer time)
