HI,
I have PGDM from one of the premier B schools in india (it generally appears in top 20 in any ratings). I have 4 yrs work ex after MBA. Now, I am thinking that i am in a kind of inertia in my career and am planing to do another MBA from top 10 bschools abroad.

My questions:

  1. Do these B schools (like Wharton, INSEAD) accept students who already have an MBA?
  2. Having an MBA, is it an advantage or a disadvantage while getting shortlisted by these institutes?
Your responses will be of great help.

Thanks.
