As the assistant branch manager, you assist the bank manager and oversee branch operations in their absence. In addition to working to manage staff and answer questions for customers, your duties could include ensuring compliance with banking standards and regulations, overseeing sales of loan products or other financial instruments and services, and covering for a teller or other customer-facing employee in the event of an unexpected absence. Your responsibilities may also consist of stepping in to solve problems or complaints that require management-level insight.
