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 — Classic Interview Problems

Covers producer-consumer, readers-writers, dining philosophers, deadlock detection, memory allocation, page replacement, and scheduling problems as interview prompts.

2 — System Design Connections

Covers how threads in web servers, process models, database memory management, scheduler impact on latency, caching/paging, and storage systems connect back to OS fundamentals.

3 — Linux Interview Questions

Covers common Linux questions, debugging scenarios, process investigation, memory leak investigation, high CPU diagnosis, the OOM killer, and kernel panic basics.
