Attention S&T!!

I am an incoming Summer Analyst at a BB within the Sales and Trading division. I am wondering what desks are ideal to sit on, during three rotations. I am interested in Fixed Income in both Rates and Credit. Love global macro so FICC would possibly be ideal as I come from an Econ and Political Science background. I would love to learn more about the different products within Fixed Income. I would love to hear thoughts on various Fixed Income desks to possibly rotate on, paths, and exit opportunities in Fixed Income. I am also open to Equities, possibly a desk within derivatives. I find convertible bonds extremely interesting as well. More insight on Equities would be helpful. Any information about various desks will be extremely helpful. Would love to learn more about the exit opportunities of various desks and long-term trajectories.
