Coding Interview Prep: Calendar Algorithms and System Patterns

Cracking the technical interview requires more than just memorizing syntax; you need to master the underlying algorithmic patterns behind real-world applications. Calendar features, such as scheduling events and detecting conflicts, are classic interview topics that test your ability to work with complex data structures and time-based intervals. This written course breaks down these challenging concepts into structured, easy-to-digest explanations. You will start by learning foundational definitions, essential time complexity concepts, and how to represent intervals programmatically. From there, you will explore core algorithmic patterns like the sweep-line algorithm, boundary-match techniques, and efficient sorting strategies for overlapping events. By studying these structured patterns, you will build the problem-solving intuition needed to tackle unfamiliar system-design and coding questions confidently. What you'll learn: - Understand foundational interval and time-representation concepts for algorithmic problems - Master the sweep-line algorithm to efficiently detect overlapping calendar events - Apply sorting and two-pointer techniques to resolve complex scheduling conflicts - Design optimized data structures to store, query, and update calendar intervals - Practice analyzing time and space complexity for interval-based interview questions - Learn modern code formatting and clean-coding principles to write readable interview solutions This text-based course guides you step-by-step from core definitions to advanced interval-merging strategies, complete with clear code snippets and conceptual breakdowns. It is designed specifically for software engineers and computer science students preparing for technical interviews, requiring only a basic understanding of programming fundamentals.
