What's your background? That will determine the type of questions you can expect. Straight out of undergrad then know bond basics, where the yield curve is and how it has moved for the past year or two, general economic forecasts, and have a couple tidbits about different credit sectors you have an interest in.

A couple years out with relevant experience then you better be able to talk more specifics and which sectors have value and be able to back up any opinion you have with a good story.
