BellSystem24 served as a guest speaker in Career and Psychology Seminar, one of the required classes for third-year students in the Department of Human Welfare at Otsuma Women's University's Faculty of Human Relations. The curriculum aims to review past learning and plan future initiatives. We titled the second of the 15 sessions "Learning career from businesspeople 1: Learn the manners required for work." Our lecture focused on how others perceive your behaviors as a basic perspective for business manners based on the knowledge cultivated through our contact center business, not limited to general knowledge.
