+## Q&A
+
+### What is the purpose of repository?
+
+To learn, of course :)
+
+### Are these real DevOps interview questions?
+
+Well, first of all, most of the questions in this repo aren't really DevOps questions. They are operational, development, HR, ... questions. Probably less than 1% percentage are actual DevOps questions but whether we like it or not, some interviews include them and this is why they are in this repository.
+
+Also, coding-operational-HR-...-interview-questions is too long name for a 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?
+
+Excellent question. We are exploring it [here](prepare_for_interview.md)
+If you have any idea how, please contribute to that file :)
+
+### Why there are no answers to most of the questions?
+
+Because we need more contributors ;)
+Also because the maintainer really likes to ask questions and less answering them :)
+
+### Can I add questions and/or answers?
+
+I'll simply imagine you didn't ask that on an open source project...
