Summer Internship: which trading desk should I consider to start?

I am a incoming summer intern in a BB and I'm unsure which desk I'd like to work on. Anyone has any idea about how I should decide? It's important to note that this BB does not have a rotational program.

I'm thinking about rates, options, FX or EM, but unfortunately due to the lack of information that I have, I am not able to narrow down my choices.

Could anyone please explain me how many different desks there are and how can I find the best option for me?

Thank you
