Operating Systems for MAANG Interviews

A book-shaped table of contents for operating systems at MAANG interview depth: foundations through processes, threads, concurrency, CPU scheduling, memory management, file systems, I/O, security & isolation, Linux internals, cloud/Kubernetes/observability, advanced kernel topics, and interview preparation — cross-linking existing sre/linux-networking, kubernetes-security, and patterns/concurrency notes instead of duplicating them.

1 — OS in Cloud Computing

Covers virtual machines, hypervisors, containers, microVMs, and resource isolation.

3 — Operating Systems for Observability

Covers process metrics, CPU metrics, memory metrics, I/O metrics, context switches, syscalls, and eBPF observability.

1 — What is an Operating System?

Covers the evolution of operating systems, the goals of an OS, types of operating systems, kernel vs. user space, monolithic vs. microkernel vs. hybrid kernels, system calls, and the boot process overview.
