Technical Assessment & Hiring
A leading technical assessment platform for hiring developers and technical talent, used by enterprise engineering teams worldwide.
Market position: Top-3 global technical assessment platform
Target buyers: Talent acquisition, engineering, and L&D teams at companies of all sizes hiring developers and other technical roles.
The Challenge
Starting position
- ●14% win rate in AI-generated head-to-head comparisons against CodeSignal, Codility, and HackerEarth
- ●Industry-leading question library and AI-powered plagiarism detection were invisible to AI recommendation engines
- ●Engineering leaders asking AI for assessment tool recommendations were consistently pointed to competitors
- ●Crowded 7-competitor market with no differentiated AI search positioning despite enterprise-grade infrastructure
The Approach
What Rex did
- ●Deployed 13 topic agents across the full spectrum of technical hiring queries — startup assessments, enterprise pair programming, AI screening, and pricing
- ●Built 85 content pieces matching the exact evaluation frameworks AI models use when comparing developer assessment platforms
- ●Targeted high-intent segments: startup-specific needs, AI-powered proctoring, and direct pricing comparisons
- ●Structured content to highlight unique differentiators — plagiarism detection, question library depth, enterprise security
Growth Trajectory
Key Results
