AI skills are now among the most valuable a candidate can list, and among the hardest to judge from a resume alone.

Review resumes and LinkedIn profiles, you’ll see “AI proficient,” “Advanced ChatGPT,” “Prompt Engineering” and “Agentic AI” everywhere, with certifications multiplying just as fast. But none of those labels tell you how well someone can apply AI to real work.

Take two candidates who both list “Agentic AI”:

One earned a certification. They know the terminology: agents, workflows, prompting, orchestration.

The other built an agent. They can connect it to tools, troubleshoot it and improve it until it delivers.

On paper, they look identical.
