Advance your impact in HR by building practical AI fluency—understanding core concepts, distinguishing between major AI types, and applying them to real workflows.
Build a clear, practical understanding of AI fundamentals by defining AI, machine learning, and task automation, then differentiating generative, predictive, and agentic AI—and where each is most useful.
Apply AI to high-impact HR work by exploring practical use cases across hiring and onboarding, employee experience and communications, and engagement and feedback—while building the judgment to use AI responsibly through clear principles, high-risk scenarios to avoid, and safe starting points.
I love that it's personalized. When I'm stuck, I don't have to hope my Google searches come out successful. The AI mentor Cosmo knows exactly what I need.

I tried Leetcode but it was too disorganized. CodeSignal covers all the topics I'm interested in and is way more structured.
