* Participate - there are great DevOps communities. I especially like [Reddit DevOps](https://www.reddit.com/r/devops). Visiting there, I learn quite a lot on different topics.
* Share - This is one of the reasons I created this project. Primary goal was to help others but a secondary goal quickly became to learn more. By asking questions, you actually learn better a certain topic. Try it out, take a certain subject and try to come up with questions you would ask someone to test his/her skills.
Well, from everywhere - past experience, colleagues, contributors, ... But please note we do not allow copying interview questions from interview questions sites to here. There are people who worked hard on adding those to their sites and we respect that.
It's a hard question and the reason is that if you'll ask 20 different people, you'll probably get at least 10 different answers but here is what we believe is common today:
* OS - DevOps require you good understanding of operating system concepts. The level required is mainly depends on the company although in my opinion it should be the same level. You should understand how the operating system works, how to troubleshoot and debug issues, etc.
* Coding is part of DevOps. The level again depends on the company. Some will require you to know basic level of scripting while others deep understanding of common algorithms, data structure, design patterns etc.
* Cloud and Containers - while not 100% must in all companies/positions, this skill is on the rise every year and many (if not most) of the positions/companies require this skill. This specifically means: AWS/Azure/GCP, Docker, Podman, Kubernetes, ...
If you don't like some of the questions or think that some questions should be removed you can open an issue or submit a PR and we can discuss it there. We don't have rules against deleting questions
Same goes for copying questions from sites to this repository. We saw it happened already with a couple of pull requests and we rejected them. We will not allow to copy content from people/sites to this repository.
The purpose of the questions in this repository is to make you learn about a certain technology or purpose. I don't believe installation questions like "How to install Jenkins?" for example, teaches you anything value on Jenkins itself.
For beginners, I recommend [Linux Journey](https://linuxjourney.com)
If you want to deep dive into operating systems internals, I really recommend [Operating Systems: Three Easy Pieces](http://pages.cs.wisc.edu/~remzi/OSTEP)
