About your goals: Whatever you aspire for in the future, why can't you start those roles from Next monday?
Think about it this way: what are the challenges you will face in that setting? What are your handicaps that you will be exposed to while doing that.
In addition, I saw the list of the school, however, I could not see a list of the employers that you are targeting. Do you know what companies you want to work for? Sears? Rotational leadership programs( Cross Functional Leadership programs). Or are you considering places such as Dupont? GE and Johnson and Johnson will have marketing cum/Sales programs. Both are amazing as the exposure to the global leadership will come with a strong learning curve. However, at your age, and with your work experience, schools want more mature thought process. Be specific ! Tell them why can't you start these roles from next Monday( Figuratively speaking), and be specific about what will a school do for you.
Also remember, some of these firms( Johnson & Johnson and GE) hire from international schools, rotate you around the globe for two years, and place you back in India at salary higher than those offered to IIM Grads( Not sure about ISB).
When did you finish your masters? Which year?
