I had interview similar to this last year. I was interviewing for back end engineer. I know SQL, Java, Python and Data warehouse fairly well. Guy interviewing was some Indian who always lives in his head. He started asking me deep Administration questions when role was clearly for engineering. I know some superficial DBA stuff but I am not DBA. Than rude stupid asshole was clearly not paying attention when I was answering questions. This is not something against Indian people but here is general piece of advice. --> be polite

--> don't copy and ask questions posted on internet.

--> don't live in your head and assume you know everything.
