NeetCode

NeetCode provides a structured curriculum for technical interview preparation, handpicking 150 essential algorithm problems and grouping them by pattern. Each problem includes a video walkthrough, and the platform now offers AI-driven mock interviews that give real-time feedback on your solutions. With over 25 hours of video explanations, it balances breadth with depth.

Great for developers who want a guided path through interview prep without drowning in problem choices. The pattern-based organization helps you recognize problem types and apply templates, which is especially useful for interviews. The newer AI interview feature adds interview-specific practice without waiting for a peer.
