Banks are divided into personal banking department, corporate banking department, personnel department, post-supervision center, audit department and accounting department, branch business department, computer department, administration department and other departments, and the head office will also have risk control department and transaction department.

Students majoring in mathematics can choose risk control department, trading department and computer department (technical support department)

There are many courses in finance. If you want to enter the bank, you must read the main books. As for how banks take the exam, there is no unified statement. All I have to do is study related courses. I suggest buying books for myself.

Basic theory books include:

western economics

Financial statistical analysis

corporate finance

Introduction to insurance

Specialized courses mainly include

money and banking

Modern monetary and financial theory

Central Bank Theory and Practice

Financial regulations

International settlement

investment banking

Financial engineering, etc.

I hope it helps you a little ~
