eSkill vs. Codility

eSkill is a pre-hire skills assessment platform that helps HR teams and hiring managers hire better. By testing the actual skills that matter for each role, hiring teams can identify high-performers, reduce time-to-hire, and decrease early employee turnover. eSkill tests focus primarily on non-negotiable hard skills, like whether a candidate can use Excel, read blueprints, understand medical codes, and demonstrate other job-specific knowledge.

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.
