the new third board department (which should be "OTC market department") of investment banks of securities companies should be engaged in investment banking business, such as due diligence and recommendation listing of new third board enterprises. The accounting work of the department itself is not only simple, but also should be unified in the company's finance department. So I guess you need to know something about stocks and capital markets.

After CPA, it will be helpful, and you will get started quickly when you do the basic work of investment banking. What needs to be supplemented is the professional knowledge of law and capital market. Don't worry, you have to take the securities qualification exam anyway.
