Ratings Agencies

What are your thoughts on working for S&P/Moody’s/Bradstreet in a quantitative role? I guess it’d be nice to see what people in ER/AM think. Do people coming out (especially now) of these agencies get looked down upon by HFs and the like? Or does it depend on what you actually did?

Note that I’m not talking about credit analysis. I’m talking more about risk management/quantitative units of these firms.
