It's actually an internship, not a formal job. Don't be so entangled. Guotai Junan Investment Banking Department can learn a lot, which is more professional. The Shanghai Stock Exchange doesn't know which department you are going to, and there may be more theoretical things. It depends on your own interests. I suggest you choose the department you are interested in.

If you have any questions, please feel free to consult the enterprise knowledge platform of Guotai Junan Securities Shanghai Branch.
