Frage im Vorstellungsgespräch bei 7-Eleven

Basic questions on React.js non jsx syntax, client vs server side rendering and coding using non jsx syntax. Interview was arrogant. Got no patience to listen to what you explain. You must speak what's he's expected else he get irritated and tells you will be rejected. Even if you are not familiar with some outdated concept, interviewer questions on same and asks to code on same since he's not familiar with anything else.
