Not worth it.
1. Not a regular employee. The bank's credit card center is not under the responsibility of the local bank, but is under the management of the head office. Generally, they do not work in the bank. The contract is not signed with the bank, but usually with a third-party company, and is not a formal employee of the bank.
2. Low wages. The job in the bank's credit card center is not very valuable, just a simple salesperson, the salary is low, and the salary depends on the performance. The more cards you do every month, the higher the commission.
