# Clear code. Beautiful code. If you don't learn to write expressive and beautiful code, no one will talk to you and you won't get hired - you simply won't pass any screening at any serious company. They'll reject you for this sooner than if you hesitate and slowly solve an algorithmic problem. There's not much to recommend here, the industry has iron classics that you need to read, study, and follow. Three books for you: * Robert Martin "Clean Code: A Handbook of Agile Software Craftsmanship" * Robert Martin "The Clean Coder: A Code of Conduct for Professional Programmers" * Steve McConnell "Code Complete: A Practical Handbook of Software Construction" Don't forget – Take the damn notes! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
