The interviewer presented the scenario: "You have a large application.log file, and you need to find all lines that contain the word 'ERROR', but you want to exclude any lines that are 'DEBUG' messages (as debug logs can sometimes also contain the word 'error' in their payload)." How to fetch logs having "error" and it should not have "debug"?

It was hilarious: the recruiter printed out 3 leafleats just before he came to the interview. One about Jenkins, one about AWS and one about Kubernetes. They told me to explain what I know because they are going to underline the words that I'm saying. This is what they did.
