best prep for MM FIG internship?

Hey guys.

So I have seen a bunch of useful information on here concerning how to prep for IB internships, but most of them seem to cover product groups at (LevFin, M&A), and less seem to focus on specific industry groups.

This spring I will be interning at a MM in their FIG office, and was wondering what I should be doing now to ensure that I'll be ready to hit the ground running. I know FIG is pretty unique, and was wondering if anyone had some advice.

Thanks guys!
