A curated collection of free resources for learning Low Level Design (LLD) / Object-Oriented Design and preparing for LLD interview rounds.Is this a tutorial, a problem set, or both?It is both: conceptual notes on OOP, design patterns, UML and concurrency, plus a graded list of machine-coding interview problems with solutions.
It is both: conceptual notes on OOP, design patterns, UML and concurrency, plus a graded list of machine-coding interview problems with solutions.Where should a beginner start?Start with the 'How to Learn LLD' guide and the '15 Must-Know OOP Concepts' section at the top of the README, then move into OOP fundamentals and design patterns.
