Need Help! Interview for Summer Analyst Position with Private Debt/Credit

Hey everyone. I'm currently a Junior at a top undergrad studying Economics. I'm interviewing for a Summer Analyst role at a Private Debt/Credit Arm of a large Fund (they also have private equity, cap markets, real estate, etc.) They deal with high-yield, non-investment grade. I'm at an undergrad with a top b-school but I'm in arts and sciences studying Econ (minoring in business tho). I have decent internship experience and am grinding to get my accounting and valuation down. Any tips for the interview? Should I know about revolver loans and other specific debt knowledge?
