DevOps SAP interview experience

I was too disappointed by this interview, they asked anything & everything. At the end, i know ill be working on either one aspect of DevOps, but SAP ppl went next level. They asked me in depth of IaC, monitoring ( inside set ups, tracing & all), codes including boto3, ansible, aws complete, java app deployment & all aspects of it, jenkins both syntax & declarative pipelines. Linux (i am good in linux), k8s almost everything on low level, TLS & SSL stuffs.

I just don’t understand y they expect one person to be expert in everything. Isn’t this too much for one person? At the end, ill be either working on TF, scripting, cicd or something else. But none of the companies i have worked in all tools at once.

Sometimes i wish i was just into dev🤦🏻‍♀️
