Tricky as this question is, it provides a great opportunity for you to demonstrate to the interviewer your courage, conviction and logic. Don’t beat around the bush or try to make up an answer; your interviewer will immediately know you are not being honest. “Give a genuine answer and describe an example of disagreement with your senior in the past, where you had put your viewpoint across. What your interviewer also wants to know is how you resolved this issue. So be sure to describe how you handled the disagreement with maturity and how you maintained professionalism and a cordial relationship afterwards.
