Ask how they drive measurable hiring and business outcomes: scope, proof, adoption, speed-to-impact, and what changes in recruiter/manager behavior.

Good questions: How do you find differentiation vs competitors? How do you build proof (not just claims)? What do recruiters and hiring managers get that they can use tomorrow? How do you ensure adoption (training, templates, QA)? How fast do we ship first assets into workflow? What does success look like at 30/60/90 days? What will you not do (to avoid fluff)? And how will the rest of the C Suite be impacted positively by this work?
