I was selected for 1st round and interview is also having good knowledge and good behavior. 2nd Round was also technical where He asked for parsing nested JSON and then he asked one question react to check if its correctly defined. I asked him I have 1year of exp in React and I have worked on Functional Component only. He told what is that functional component? I haven't heard on this. It was so embarrassing that the interviewer itself is weak on React. He argued on Class vs Functional and the dumb answer he told we use hooks in class component. and rejected me.
