Operating System Concepts for Technical Interviews

Landing a software engineering role requires a solid grasp of how computers manage resources under the hood. This text-based course breaks down complex operating system concepts into clear, interview-ready explanations, helping you confidently answer technical questions. By reading through these structured lessons, you will transition from a basic understanding of computer hardware to a deep conceptual knowledge of how modern operating systems coordinate processes, memory, and storage. You will gain the vocabulary and theoretical background needed to articulate solutions clearly during system design and technical interviews. What you'll learn: - Understand the core responsibilities of an operating system, including the kernel, system calls, and user space. - Analyze process management, thread execution, and modern CPU scheduling algorithms. - Solve concurrency challenges using synchronization primitives like mutexes, semaphores, and locks. - Master memory management strategies, including virtual memory, paging, and caching mechanisms. - Explain file systems, storage allocation, and input/output communication protocols. - Explore modern containerization concepts, focusing on OS-level virtualization, namespaces, and resource control. The course begins with foundational definitions and key terminology before guiding you through process synchronization, memory allocation, and modern virtualization technologies. Each section includes conceptual review questions designed to mirror real-world interview scenarios. This course is designed for aspiring software engineers, computer science students, and self-taught developers preparing for technical interviews, with no prior OS knowledge required.
