The bank credit card salesmen I have contacted are: China Merchants Bank, Bank of Communications, Xingye, Huaxia, Pufa, Guangfa and so on. It seems that there are many commercial banks, and the five major state-owned banks rarely contact each other.
As far as the credit card salesmen of commercial banks are concerned, the overall feeling is that China Merchants Bank, Xingye Bank, Bank of Communications, Shanghai Pudong Development Bank and Guangfa Bank are all quite good, and their quality is relatively high. They were told that it was working hours and would never be disturbed. Instead, I choose the rest time to carry out the promotion work, hold the list of credit card products, and repeat "Do you want to apply for a card" over and over again. Talk directly to those who need to apply for a card and introduce the characteristics of each product. If there is no intention to apply for a card, they will also politely say "Excuse me, thank you".
Other banks have less contact with credit card business and have no right to speak.
