For senior AI Engineer interviews

Twenty-one weeks from rusty to ready.

Learn first, then drill

Each week's modules come with curated reading. Flashcards unlock only after you've studied the theory.

Built for 2026 loops

Evals, LLMOps, inference and scaling, agents, MCP and safety, alongside NeetCode 150 and design cases.
