Preparing for technical interviews at top-tier companies requires more than just memorizing algorithms; you need to understand how real-world systems are built. This course bridges the gap between theoretical computer science and practical system design by breaking down the core features of major social media platforms. Through clear, written explanations and structured code walkthroughs, you will learn how to approach complex engineering problems and articulate your solutions clearly to interviewers. You will transition from writing simple scripts to designing scalable, efficient architectures. What you'll learn: * Understand the foundational concepts of system design and data structures used in social media * Implement efficient algorithms for news feed generation and activity feeds * Design scalable relational and non-relational database schemas for user connections * Apply modern caching strategies and rate-limiting patterns to handle high traffic * Practice solving common graph-based coding problems, such as finding mutual friends * Learn how to structure your communication during technical interviews We begin with key terminology and the basic building blocks of system architecture before diving into step-by-step feature breakdowns. You will explore practical, text-based examples that illustrate how to scale services and optimize data retrieval. This course is designed for aspiring software engineers and developers preparing for coding interviews.
