Hi,
Why don't you try IIM's Fellow Program In management? / any of the top 10 B-schools...??

There are many University offering the same along with IIMs The eligibility criteria is to appear for Net, or Mphil degree for most of the Universities.
FOr IIMs one has to clear the CAT or GMAT, and on the basis of the scores that institutes take the candidates for fellowship. IIT Delhi also offers PhD in OB.
