Capital Group Fundamental Research Associate

I’m in the interview process for CapRe’s Fundamental Research Associate position, specifically on with the Muni Bond team. Could someone please walk me through the interview process including the following:

1. What does the ~3 hour modeling test comprise of? Does it differ for Muni roles at all?
2. Any advice on preparing for a Muni Research role? I’m well versed in muni bonds, but don’t know how to prepare across sectors(I.e. Healthcare, Project Finance, Utilities, etc.)
