Preguntas de entrevista para el puesto de Senior Software Engineer en WorkSpan

Total 3 round was there. In first round the interviewer asked Soma basic JS questions and a problem solving questions. In the second round the interviewer was confused, he asked me some js, React and Webpack related questions and then he asked a problem solving questions, which I solved. But the interviewer want me to implement the solution which was running into his head. He agreed that my approach is right but can I solve it with a approach running into his mind. So in my case either the interviewer was unqualified or he was biased with some other candidates. Workspan was my dream company once. Hope they improve on this. I will not interested in join them any more.
