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 — Race Conditions

Covers critical sections, atomic operations, compare-and-swap (CAS), load-link/store-conditional (LL/SC), and memory visibility.

2 — Deadlocks

Covers the necessary conditions for deadlock, prevention, avoidance, detection, recovery, and the Banker's algorithm.

4 — Memory Ordering

Covers CPU reordering, compiler reordering, acquire/release semantics, sequential consistency, memory fences, and happens-before relationships.
