Hi Abhishek,
I am not sure whether you already made up your list or are still in planning phase.
I am an MBA graduate (SDA Bocconi, Batch of 2011) and had about 3.5 years of experience when I entered my MBA.
Regarding schools, I think you would have already heard of the perfect recipe of applying to 6 schools (2 - Dream, 2 - Within reach, 2- Sure shot)
I think that works quite well.
Another suggestion which I have is not to just think about schools based on their rankings. Try to think what you wanna do after your MBA and I am certain your choices would change based on that. I am trying to share my experience with people and trying to give good reasons to think before making any choices.
Going for an MBA is a very crucial choice and needs a lot of consideration, specially in choosing the school.
I think you are bit short on the experience front, but you have a great GMAT (although that's not the only criteria). But most likely ISB you will definitely get as GMAT is the major thing they look for. I would suggest go for better schools based on your career plans.
Let me know if you need any help with choosing the school or planning for your MBA.
Cheers !
