As a Personal Banker with First Commonwealth Bank, you will be dealing with a wide variety of clients and your interviewer will be looking to hear that you are able to tailor your approach to working with many different personalities while maintaining a knowledgeable and professional approach with each person. In your answer, be sure to stress that you have the patience to work with all different types of people effectively and the calmness to handle customers that are demanding or full of questions. If you have an example of a role you've held in the past where you've worked with customers, feel free to bring examples of times you had to work with differing personalities first hand.
