Codility vs. Twiser

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.
