I have worked in the financial services industry for many years but have never worked at a bank. My role today is relationship management for a technology company that provides on line banking and other services for banks. In all of the roles I've had, I have learned and continue to learn about the banking industry. Banking provides a number of opportunities from entry level on up: teller, loan officer, retail banking, digital, risk, compliance, operations and more. If banking is of interest, remember, it's not limited to a bank per se. As with banks, many companies that provide services to banks offer internships as well. Good luck.
