Read the guide →How this library is maintained
Built for practice, reviewed for usefulness.
Each guide is written around a decision candidates actually make, then checked for a clear method, realistic examples, and prompts that can be practised aloud. We revise pages when a framework is unclear, a recommendation needs more context, or readers point out a gap. The guides are educational resources, not hiring advice or promises about interview outcomes.
