Interview Sogen Societe Generale

I have an interview with Societe Generale FICC for a quantitative analyst position. I know a decent amount about options and I guess I know sort of know the basics about the market, but i don't know that much about FICC stuff in general. I mean should I have a canned answer as to where I think the dollar/euro rate is going? Should I know bond convexity hands down? Any advice would be helpful.
