Secondly, although entering the counter is a chore, you need to master much more than customer service. Reconciliation can't be wrong. I am very busy every day and often work overtime because of reconciliation.
Above, investment, wealth management, loans and other departments are more comfortable.
Anyway, customer service is a very low-end job because there is no risk of touching money or customer accounts.
And you have to be qualified to enter the counter, not so casual, like an accounting certificate.
