IsCoolLab interview questions

homework assignment for 1w, review of homework for 30 min, tech interview for 1hr culture fit for 1hr I was failed at second round, the review round be hold with few manager and lead, but it mainly host with few junior devs. I use vite-electron to implement it, to get puls points "use electron", "not use create-react-app", I was thinking the assignment is just to prove I know how react/redux works, then in interview they ask about why my electron be setup like that(it be generated by template...), and why I don't define types for reducers, but when I developing there is no warning for reducer without types, and they review it in an environment without node, what the hack? I told them in past 2 years I didn't use redux, but after check latest document, its pattern is similar to old one but cleaner. I use Sass to implement the styles, and a junior ask why not use styled-component, I answer I used to use sass in recnet jobs. Then I got feedback: "not familiar with new tools"
