why this exists
Most interview prep content stops at definitions. Real interviews don't — they push into trade-offs, failure stories, and the follow-up behind your first answer. This hub was built the way interviews actually run: every question has a model answer you can defend, the follow-ups an interviewer actually asks, and the trap most candidates fall into.
It covers the full DevOps surface — core concepts, CI/CD, containers, cloud, infrastructure as code, Linux administration, version control, monitoring and networking — plus scenario-based mock interviews for senior and SRE loops.
Whoever you are — first job or principal role — start where you can answer without notes, then keep climbing.

how it's organized
Twelve sections, four levels each — every section opens with a getting-started guide and closes with a master collection holding the complete raw bank. The getting started page maps a suggested order through all of it.
the figures
The illustrations across this site are drawn with text characters — timelines, checklists, tables and small charts. They render as live components here and stay readable as plain text anywhere else.
who's behind it
Built and maintained by HARSHHAA, a DevOps engineer, with contributions from the community. The content is open source — fix an answer, add a question, or propose a whole section with a pull request.
