Fixed Income Research - Entry level, Final Round Interview Advice

I recently graduated from a semi-target school in Canada and made it to the final round for a Fixed Income research position in an HCOL city.

The firm is based out of MCOL city in the US and I have a 3-4 hour final round interview with some senior members of the team next week. I've covered my basis and studied most behavioural/technicals but I don't really know what to expect since this will be my first time doing such a long interview. I believe the team in Canada is relatively small and covers corporate and muni/federal bonds, what sectors should I study/cover.

Also, should I be prepared to analyze a financial statement or pitch a bond/stock?

Any help would be appreciated.
