A significant portion of your time will be spent identifying potential risks and ensuring that internal controls are operating effectively. Collaboration is key; you will frequently engage with cross-functional teams to resolve discrepancies, meaning you must be able to communicate effectively even when your findings might be met with resistance from stakeholders.
