Hm. I have mixed feelings reading this. I'm a very experienced Linux admin that rebranded to DevOps, and I can tell you no one outside of government/academia or slower organizations like (some legacy groups within) banks cares about your awk and zsh skills, or even kernel internals. They do care about coding, very very much. I get slammed with coding challenges, sometimes even before talking to a real human, and once three separate rounds, in interviews. Think they care you can set up a mail server, troubleshoot IO issues, read a tcpdump. Well the answer is they might. But Docker, extensive AWS and Python or Ruby at the software engineer level? They will. RIP systems administration and RHCE relevance. Don't waste your time if you're looking for a new job, for instance. Your time is better spent on the examples above. And soon, Kubernetes.
