This page provides you with application and interview advice provided directly by graduates working at Post Office
Application advice: Talk up anything you know about process or continous improvement (LEAN). Using this to save costs and work efficiently is useful. Also research centralising services like finance and HR, because this is the big move most businesses are taking. Finally, talk up what you know about managing performance and how you would ensure performance was as it needs to be.
