Duke probably has the best reputation in the South, but most graduates went to other cities (you can check job placement report). In these days, if you are in any of top-10 U.S b-schools, you will get interview chances with any top consulting firms, Mckinsey, Bain, BCG, etc. At the end of the day, school will only provide the opportunity for you, after that, it really depends on your own skills.
If you have any other questions about Duke, please feel free to ask here.
