Codesignal’s AI agent draws on tens of thousands of hours of talent science research to create simulation-based, role-specific assessments and interview content on demand

SAN FRANCISCO, April 28, 2026 /PRNewswire/ — CodeSignal, the leading AI-native skills platform, today announced that any hiring team can discover or create expert-level skills assessments and interview content on demand with Cosmo, its AI agent. Applying research and frameworks from CodeSignal’s Talent Science team, a group of I-O psychologists who design and validate job-relevant assessments, Cosmo brings that same rigorous process to any role instantly.

“Building high-quality skills assessments and interview questions is hard,” said Tigran Sloyan, Co-Founder and CEO of CodeSignal. “Our team of I-O psychologists develops the science behind what makes a great skills assessment, and thanks to AI, we’re now delivering that expertise at scale and speed never seen before.”

Creating skills-based hiring content requires knowing which skills matter for a role, designing exercises that surface those skills, and applying science-backed rubrics that stay consistent across every candidate. That expertise lives inside a library of 1,000+ certified assessments and 4,000+ questions using role-based simulations spanning coding, writing, spreadsheets, and conversational scenarios—and all validated for job relevance, fairness, and compliance with employment standards.

How to work with Cosmo:

• Content discovery: Describe the role, or copy and paste a job description, and Cosmo surfaces the best-fit assessment or question from an extensive library of certified assessments and questions across business and technical roles
• Custom creation: When custom content is a better fit for your role, Cosmo builds assessments, AI interviews, or live interview questions of all types, with the ability to give feedback and refine as you go
