As a senior teller, your responsibilities are to provide customer service at a bank branch, process banking transactions, and oversee junior tellers. You handle deposits, help customers withdraw money and check their balances, answer questions about accounts, and direct customers to other bank staff for more specialized services or advice. You may also train new tellers and other front-end staff in bank operations and customer service procedures. In some branches, your duties may include scheduling tellers and auditing their performance.
