My Friend there are two parts to the answer to your question-
Eligibility & Admission Success
PART 1- Eligibility
One year program in ISB requires a graduation degree, 2+ years of ex years of work ex, a valid GMAT score. If you have all of the above you are eligible to apply.
PART 2- Admission Success
Just having a GMAT score (even if it is high) does not mean you will get an admission.
Getting into ISB can sure be daunting. But it is quite simple to break down what the admission committee is looking for in a good candidate.
What is the Admissions committee looking for?
Admissions in ISB happens on basis of GMAT, Essays, Recommendations & Interviews.
A combination of these four pillars helps the admission committee judge the applicant on primarily six parameters-
1. Academics- Past Scores + GMAT to judge if you can handle the academic rigor.
2. Work Experience- CV, Essays and Recommendations will display your relevant quality work ex.
