The qualifications that you need to start a career in a bank call center include excellent customer service skills, knowledge of bank products and procedures, and a high school diploma or GED certificate. Employers may prefer applicants with a finance-related degree or applicants who have completed finance courses in college. Other requirements may depend on the responsibilities of your job. A call center supervisor may need management experience or a degree in business administration or management. Employers may also require new call center workers to undergo customer service training before they work independently.
