Credit Rating Agency FIG Group to EM Sovereign Group?

Currently interviewing at a top 3 credit ratings agency. Vacant position is in their FIG group. I'm wondering how easy it would be to transfer from FIG to an Emerging Market Sovereign debt group. It's an area I'm genuinely interested in and I believe would utilize my economics background (postgrad level). HY debt in particular I imagine would provide a wider variety of skills and be more interesting in general.

For what it's worth, the interviewers told me straight up that it was fairly easy to move between groups as long as you do it early ish in your career. They also mentioned that the skills you learn in FIG are fairly transferable to a sovereign group. Could anyone confirm this?
