Your interviewer is trying to determine whether you are invested in competing for this opportunity or are simply trying to find any job with anyone. Questions such as these are useful in distinguishing those who identify with their mission statements, values, environment, and work culture. The path forward with this question is to familiarize yourself with their purpose statement, which says, "Our purpose - opening up a world of opportunity - explains why we exist. We're always looking for people with purpose and ambition who can help us build a bank fit for the future." After familiarizing yourself with their statement, look at your professional life and the purpose for choosing your career path. Examine what you find most rewarding about your profession and try to align it with their purpose statement.
