Waiting for another year and dropping NMIMS is only justifiable if you are certain to get into the top 5 like IIM ABC and FMS. Otherwise forgoing this opportunity might not be a wise decision mainly because
Moreover, if you are willing to enter the Marketing sector, it’s still not late as FMCG don’t prefer candidates with much work experience. But if you are interested in Strategic Management, you can wait for a year and target the top 5 B Schools.
So the end note is, forgo the offer if you are certain you can make it into the top 5 else grab this opportunity.
