Perguntas de entrevista de vagas de Software Engineer, Backend da empresa WAES

First one very good non technical Skype interview. Then a code assignment with unclear and confusing requirements. The code feedback was just some general non meaningful non understandable points about the code. I asked for clarifications and the reviewer mail just add more confusion. Even started to think that he didn't review my code. For example: "you put bussines logic into the controller" and it was totally false , only a call to a service in each endpoint. I didn't get to the technical interview but I still wonder what the reviewer reviewed...
