Bank Clerk Question:

Nothing says "hire me" better than a track record of achieving amazing results in past jobs, so do not be shy when answering this question. A great way to do so is by using the S-T-A-R method. Set up the situation and the task that you were required to complete to provide the interviewer with background context, but spend the bulk of your time describing what you actually did (the action) and what you achieved (the result).
