British Council would like to hear actual success stories in interviews that is relatable to the questions. Sharing hypothetical answers to what your capabilities are or how you 'would' fit for the role doesn't ring a bell for this institution. You need to share any story that you had an impact on from your past (at a university club, at an internship, at a temp job if you are applying to a junior role for example) that is in accordance to the question.
