IB Debt Capital Markets Interview Prep

Hello,

I am an undergrad at a European target school, currently looking to break into IB. I have been on several M&A and Corporate Finance interviews (for intern position) during the last week or so, in which I have experienced that many, if not all, technical questions are the same, but in a few days I have my first interview at a DCM division. The interview is case based and specifically revolves around the debt side of financing. 

I was wondering if there are any people on here who might be able to provide me with some answers regarding what I am expected to know coming into the interview? It is pretty easy finding typical interview questions to corporate finance or m&a positions but not DCM. Perhaps what a debt finance case could be about as well?

Thanks.
