Struc Fin Interview - HELP!

I have a phone interview TOMORROW for an associate position within a large and well-known insurance companies Investment Management division. Specifically, the position is not directly front-office, but more mid-office in a structured finance risk/oversight role and assists with operations surrounding their multi-multi billion dollar ABS, CMBS, RMBS and structured product/derivative portfolio.

I have an ivy bachelors (2003 grad) with a varied background that includes some corpo fin @ a Fortune 50 diversified healthcare manufacturer, equity derivatives sales @ a top-tier ibank and trading/portfolio management at a micro hedge fund. The micro fund i currently work at is shuttering in a few months (founder converting to mutual fund management. i don't want to go along for the ride) and given the tough job market (very tough!) I feel fortunate to get a chance to join a large investment management operation, even if it isn't front office. I see it as a stepping stone to a front office structuring/analyst role within strucfin/credit/etc. I made the mistake of NOT pursuing my CFA over the past 5 years due to the combination of large bonus checks and youthful ignorance. I have however decided to pursue and complete it by 2013.

I'm not worried about the technical/hard questions. I'm really worried about the soft/feeler questions. These are what will determine selection from amongst a group of well-qualified candidates. They're going to ask me questions like Why this firm (large insurance company with huge investment portfolio)? Why structured finance? What experience/value do you have to lend to CMBS/RMBS/ABS oversight and analysis?

Any advice on how to answer these questions without sounding like I am desparately licking the brown off my interviewers backside? The phone interviewer will be the woman who is running the group, so not some recruiter. Already passed that initial hurdle.

I don't want to become unemployed or risk any gap in my employment, as I know it becaomes much harder to find a job then. But I also need to say the right things, and not "i need a job, this is a great company, blah blah"

Any structured finance nuggets of wisdom to be lent my way? I'm well aware of the current illiquid and precarious (nonexistant?) nature of securitization in the ABS markets. But large holders of these investments still have t manage their portfolio risk.

Any advice is welcome. I have had a subscription to the Journal of Structured Finance for the past few years and contemplated drawing alot of talking points from that that material. Is that too much? Feel like I will blow this interview if I sound like every other chump trying to get a decent job with a well-known company in a respectable field...
