## Should I be familiar with all the tools/platforms/... listed in this repository?
### Should I be familiar with all the tools/platforms/... listed in this repository?
NO NO NO! :)
I won't give you the crap of "DevOps is a culture, not a role" kind of stuff but one thing is for sure, DevOps is not about being familiar with all the existing tools.
With that being said, there are some concepts, tools, platforms, ... that are quite common in jobs requirements. Take Linux for example. While Linux is not part of 100% of DevOps roles out there (go figure it out...) it's still quite desired skill and probably appear as a requirement in more than 80% of DevOps roles if I had to guess. So go learn some Linux ;)

### How should I prepare for my DevOps interview?
@ -27,6 +27,10 @@ If you have any idea how, please contribute to that file :)
Because we need more contributors ;)
Also because the maintainer really likes to ask questions and less answering them :)
### Where the questions and answers are coming from?
Well, from everywhere - past experience, colleagues, contributors, ... But we do not allow copying interview questions from interview questions sites. There are people who worked hard on adding those to their sites and we respect that.
### Can I add questions and/or answers?
I'll simply imagine you didn't ask that on an open source project...
