Some of my friends have been to all of the mentioned colleges to pursue their MBA degrees so based on their experience and knowledge I can answer this question.
- IIM Ahmedabad would be a better option for international student exchange programs as it has collaboration with many foreign universities for the exchange program where around one-fourth of the students are selected every year for it.
- The selection procedure is solely based on the academic performance of the students in IIM along with the extracurricular activities.
- Also, the college also has a dual term exchange program where nearly 14 to 15 students are selected on the basis of their academic performance and are granted the opportunities to go to foreign universities for their master's degree apart from the IIMs PGDM degree.
However, IIM Calcutta and Bangalore also provide the student with various International exposure and opportunities but not as great as IIM Ahmedabad. Hence IIM Ahmedabad would be a great option to go with.
