MBA/PGDM

Hello.
Harvard, as the rank & research facilities are ranked almost the highest, so is the competition level. You are required to perform in the top 1 to 5 % of your undergrad & higher degrees in academics you have done before you apply. Besides, you need a high percentile in your GMAT in order to crack admission at HBS. You will require strong essay writing skills & letter of references from your academics & employer respectively which will contribute towards making a strong application. As the Harvard's acceptance rate is under 8 to 10% only, you may have to be in top 1% of the students who look forward to apply from India. It also should speak in form of the essays, your deep desire to study in HBS & what/how are you looking at contributing to the HBS community. Since your application is made from a country which is the 2nd in making/sending students to US for their higher studies making your application highly competitive.

If you want to settle abroad, then obviously university abroad is best depending on the place you want to settle in and the best university there, but if you want to settle in India all of them are best based on certain criterias Like:
1) Your Percentage
2) Which Institute exactly?
3) simply doing it from any university abroad will not giving you any weightage in our country too.
4) And irrespective of you holding any degree from IIM, IIT and not proving yourself excellent and a wonderful asset to the company will of be no use either. So Work Smart and hard but don't slog and remember even people from government schools and colleges are idols for people and proved themselves good, so, your smart and good work is more important than the names of the institutes.
Wish you luck.
