Last week I conducted a FE React-JS tech interview (high-level, no coding challenge) with a potential new hire. He knew his stuff in React 16.8+ but I was baffled npm install was the only npm command he could name, he'd never heard about semver, never used SASS, and didn't have any Nodejs exp. I asked him to name a tough situation he encountered and solved in React, and he said "too many re-renders, so we used useMemo and useCallback" but that's kind of basic and it was evident he didn't understand this meant passing props by reference under the hood. So I wrote a very mixed report, but this is only the 3rd interview conducted. Was I too harsh? To me this signaled a lack of curiosity (especially for a self-taught programmer which he was). My manager was kind of disappointed about the guy following my report.
