I'm wondering if in personal experience interview, interviewee has to answer each question with a personal story relative to his/her background. Because sometimes questions explicitly ask you to tell about a story (e.g. "Tell me about a recent positive team experience" , "Tell me when you failed in something", "describe a time you disagreed with your supervisor" and so on), on the other hand, sometimes, questions do not explicitly ask for a story and, according to me, you can answer "theoretically speaking" and so without an example of true life (e.g. "How competitive are you?", "What do you believe is your greatest strength", "How would you describe your learning ability")
Am I right? Or I would better off by adding a short story of my life for each question (even those where it is not explicitly required)?
Thank you a lot
