Fidelity Investments interview questions

one round of panel interview Usleless questions, asking uncecessayhings that are not in the JD. Interviewers are novice and arrogant. They expect an answer that they think is correct and if you give a different answer they get irritated. This was the first interview in which a lady told me rudely to give an answer which she understands in a dumb down manner,how would the candidate know the how educated the interviewer is, the candidte will assume that if the interviewer is asking a question they should be aware of the technical nuances. secondly the interview was like an interrogation one talking over the other, asking questions that sre mentioned as nice to have but not necessary in the job description.
