DevOps Interview Kit is a free, interactive reference guide for engineers preparing for DevOps and SRE interviews. Every section is written from real interview experience — not copied from documentation.
Each tool covers key concepts, important commands, architecture patterns, and curated interview Q&As with full answers. Click any node on the mind map, read the detail panel, and you're ready to answer that question in an interview.
The mind map covers 19 tools across 10 categories — from Git and GitHub Actions all the way through to SRE concepts like SLOs, error budgets, and blameless post-mortems.
This site is run by master.devops, a DevOps education brand, focused on helping engineers master the skills and interview techniques needed for DevOps, SRE, and cloud engineering roles.
Good interview prep shouldn't cost ₹5,000 for a course. The fundamentals — concepts, commands, and how to articulate answers clearly — should be accessible to every engineer regardless of budget.
This site stays free and is supported by Google AdSense and optional resources like mock interview sessions and extended cheatsheet packs. If you find it valuable, following on Instagram or sharing with a colleague is the best way to support it.
🙏 Every ₹ and $ from ads and support goes directly into building better tools — more simulators, more Q&As, Kubernetes labs, and Python scripting guides — all free for the community.
All content is free and always will be. If this helped you prep for an interview, consider supporting — even ₹50 or $1 makes a difference.
