Rating analyst to BB credit risk interview

Hi all, Rating analyst with around 3yoe based in Europe and have a first round interview with a risk team at a BB at European office. I cover IG financial institutions and this role is within credit risk - counterparty credit risk for FI (prob non-IG included) at associate level.

I feel like the role will be focused on motivation and my FI knowledge but I think I lack some technicals needed for the role overall. I still dont have a primary analyst role and worried this will show if they start drilling into things.

Any advice how I can best prepare for this? counterparty credit risk involve derivative exposure so I guess that, how deep will they go on FI fundamental analysis from a rating perspective vs more general credit technicals like bonds / fixed income math etc. Appreciate any input!
