Interview
Overall, I think you need to have a comprehensive knowledge to ace the interview. However, with some basics linux commands and troubleshooting, you will be able to do a decent job. I feel like most of these questions where improvised. The interviewer will start asking you basic questions and he feels like you know what you’re talking about, he will go more in depth. Note there was no question in the final round about Kubernetes, Prometheus, Grafana, Ansible or even AWS even if they were all listed in my resume. It was mostly about Linux, Networking and Infrastructure concepts. The 4 interviews were:
-70% technical, 30% behavioral. Most technical questions was asking me how I did things
-100% behavioral
-100% behavioral
-90% behavioral 10% behavioral.
