I once went to Shanghai Pudong Development Building for an interview. I interviewed for credit card customer service, which belongs to the same category as your installment. Your credit card customer service seems to belong to the nature of outgoing calls, but at that time, I was paid a minimum salary of 4, yuan a month (without five insurances and one gold) with a year-end bonus. Once in January, it seems that I have signed agreements with other companies, and it will take several years to become a full member. I don't know whether it is true or not.
