first round was on interview-vector. 2nd round was again on PS/DS Interviewer was some senior SDE was egoistic guy. He thinks his point is the only valid one and keeps on pointing that throughout the interview, Whole one hour he kept on pointing how map is better than using array and I agreed with scenarios that made sense but unless I say in same manner he will not stop. Complete waste. Interviewer had some idea or picture of what the code should be or how it should look and does not see that it is passing all test cases like an idiot. He probably read the answer 2 mins before the interview. shame to see a company with such arrogant developer at senior position. also, that too when the answer of the coding ques asked were correct.
