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.
| Capability | DynaLab | Take-Home Projects | Whiteboard / HackerRank |
|---|---|---|---|
| Time investment | 2-4 hours async, 5 min scorecard review | 4-8 hours candidate, 1-2 hours reviewer | 45-60 min live |
| What's measured | Full process — verification, context, recovery | Final output only | Algorithm correctness |
| Scoring | 7 calibrated dimensions with evidence | Subjective reviewer opinion | Pass/fail |
| Reviewer effort | Minimal — automated scorecard, quick review | 1-2 hours per submission | Real-time attendance required |
| Cost per assessment | ~$3 per assessment | 1-2 hours senior engineer time per submission | $150+ (platform + interviewer time) |
