They are all telephone operation managers of credit card business, that is, telemarketing. Credit card salesmen just go out to run their own businesses. First, you must decide whether you like telemarketing or running around. The telephone operation of banks may face higher-level customers. They usually develop gold or platinum cards, and the commission for customers is also high. Those who simply handle credit cards are generally ordinary card users. The commission is just a little low. I think the salesmen of China Merchants Bank are well paid. As long as you have that determination, you are not afraid of hardship, and the future of money is boundless. I also have friends who do well in credit cards. So choose for yourself. Telephone operation manager can't be a tour guide at first. Time is much shorter than running outside.
