I think that you are too focused on the recent changes in ranking. You should visit both schools and speak to students who are pursuing a finance career, meet with alumni and read the career placement reports to get a feel on where they landed (firms, locations, salary etc). I advise that you really "study" the past placement reports and get in touch with people from Simon and Goizueta.
Traditionally, both schools are strong in finance. I have friends who graduated from both schools and work in the financial sector. Often times, the decision was more of a personal preference (family reasons or wanting to live in Atlanta for example).
I have a question in regards to which school fellow members on here would prefer. I'm currently debating whether to continue to pursue Emory or Simon for the incoming Class of 2012. Ideally, I would like to work in a bulge bracket bank straight out of school as an I-banker or go into some sort of hedge fund or Private equity. Which school would be ideal for this type of career route? It seems like for this year, Simon has moved up in ranking while Emory has fallen back, and both tie in rankings. However, Emory has historically enjoyed a higher ranking, just slightly out of the top 20 spots. All in all, I just wanted to get few inputs on which school most people on here would choose to go if they were to pursue a career in finance. Thanks
