Codility vs. Nestor

Codility is a technical and AI skills assessment platform built on documented assessment science. For almost two decades it has helped engineering and talent teams answer one question with evidence: who can actually do the work. Every task is designed by occupational psychologists, mapped to the Codility Engineering Skills Model, and monitored for adverse impact at every measured cut score. When a result is challenged, the methodology behind it is documented and reviewable. Three products run on that foundation. Screen delivers standardized early technical signal at scale.

Nestor is a skills-based people intelligence platform that helps organizations unlock workforce agility, increase performance, and facilitate employee growth. In the face of ongoing workforce changes and technological disruptions, companies cannot afford employees with outdated skills. Skills are the foundations for all of Nestor's solutions: Skills Management, Talent and Opportunity Marketplace, Career Development and Growth Journeys, Performance and Engagement.
