Evolution Javascript Developer interview questions

Most useless interview I have ever been to. - It started with a game on codingame.com, which is a "great" way to begin an interview - by solving a task in JS that you never solve in real life while working on projects. - Next it was a basic part: introduction and questions about background. - Then was 1.5 (!) hours talking about Promises and a task to implement my version of promises using TDD. (Very "useful" task). I'm not sure what this interview was supposed to prove and how it helps determine a good developer from a bad one. It only left a bad impression about the company and their employment process overall. Would not recommend.
