Preguntas de entrevista para el cargo de Full Stack Java Developer en Watermark

Profile picked up from Naukri. Interview called and scheduled my interview. I was asked whether I had experience in Java and React. I told I had 2 years experience in Java and don't have working experience of React but I have learned during my college time and have created few projects in it. After which the interview continued to take 1 hour interview where he asked Java and SQL questions. I also did some multiple small coding questions. I answered all the questions correctly. He also then asked me what the company does, but I said I am not sure as the interview was at 11 am and was scheduled just yesterday at 11:30 pm. So, I was busy preparing for interview. He definitely did not like that I didn't knew what his company does. As he is maybe there for like 10+ years, so he is probably obsessed with the company and did not like the fact that I have not read about this company. I did not heard back from them again, after multiple calls for the feedback, the HR told me I was rejected because I didn't have experience in React which is very weird as why didn't he asked me a single question of React then? Why wasted my 1 hour then if working experience is that compulsory and why didn't you asked me any question of React if it was that necessary???? Very disappointed in the way they treated me.
