Fixed Income Case Study - Interview Next Week - Help

Hey monkeys, 

I recently did my first round for a Fixed Income Analyst role for a corporate bonds fund. Was told that I'm being put through for the second round.

Second round will consist of the PM giving me a company, most likely a notch either side of IG, he wants me to discuss its credit metrics and ultimately decide whether we buy or sell its bonds. He said I will receive the case study before the interview.

What could I expect?

Thanks lads
