CodeSignal launches agentic coding assessments as 91% of engineers now use AI tools

CodeSignal has launched agentic coding assessments, designed to evaluate engineers' ability to work with AI coding tools. The move reflects a significant shift in software development, according to a March 2026 survey of 450 US software engineers. The survey found that 91% of engineers now use agentic AI coding tools like Claude Code and Cursor in their work, whilst 75% have shipped production code partially or primarily AI-generated in the past six months. Additionally, 73% believe engineers who don't adopt these tools risk becoming less competitive. The new assessments require candidates to extract requirements, use agentic AI tools to build solutions, and explain their technical decisions. Over the past six months, tens of thousands of candidates have completed CodeSignal's AI-assisted coding assessments, with roughly one-third of customers adopting the format during 2025.
