IG credit sales interview: What to expect

Hi WSO,

I was lucky enough to land myself an opportunity to interview for an entry level investment grade credit sales role tomorrow with one of the larger European banks. It came up on really short notice being that I didn't even directly apply for the role, but had a very senior person within the whole S&T division that I had managed to make a good impression on while networking with him that referred me down to his head of IG credit in NY.

What should I be expecting in this interview on both the fit & technical side of things. I'm generally pretty well versed on fixed income markets as a whole for someone who's never actually worked in a role in S&T or the buyside and it's actually the market where I want to be. 

Thanks in advance to all who are generous enough to answer.
