If your undergraduate course is relatively ordinary and your basic employment is at the grassroots level, you usually do sales work in some financial institutions (personal sales and non-institutional sales). If your school is better, maybe you can join the Big Four accounting firms and work for two years before you consider studying (in this case, there will be more MBA students), or if your job is better, you can jump ship to a brokerage firm (this method will be a bit evasive). Therefore, graduate school is a relatively direct choice.
I graduated last year with a master's degree in finance and economics. If you want to know anything, you can continue to ask. I hope I can help you.
