Hello Qualem,
My answer is for you to spend some time thinking about who you are and what you like to do. What is your personality type? Are you deliberate and like to take your time to understand things deeply? If so, you will probably enjoy working as a credit analyst, or as a long-term value equity investor. If, on the other hand, you like excitement and dynamic, ever-changing environments then you likely enjoy working as a trader, or as a short-term, growth equity investor. While you are t the French bank this summer you should ask if it is possible for you to visit other departments to see what their jobs are like. This will give you pretty good feedback for what kind of an internship you want next year.
Best wishes for success at school, with the CFA program, and in life!
