My cousin belonged to the Mohali campus of ISB and during her exchange term, she observed and compared the pros and cons of both campuses. I have listed the major pros of both colleges.

ISB Hyderabad

• Huge batch size ensures peers from a variety of backgrounds.
• The location is helpful for the students to maintain a good social life
• ISB Hyderabad has a wider range of student-driven clubs and committed
• The placement presentations take place at the Hyderabad campus and Mohali students get to join through a video call only

ISB Mohali

• ISB Mohali has very few resident faculty as it has been recently established. As a result, the institute calls in the best faculty from colleges like Wharton, UNC, and Kellogg to teach. Their pedagogy is unique and ISB Hyderabad lacks in this aspect.
• The campus is new so the accommodation facilities are better and made to suit all the necessary requirements. These hostels have better furnishing, space, and housekeeping facilities in comparison to the hostels of ISB Hyderabad.
• The small batch size ensures the quality over quantity belief
• The choice of electives is done through online bidding at ISB. Hyderabad campus with its huge batch size makes it impossible for all the students to get their choice of electives. Mohali students, in turn, face no such problem because of the small batch size

ISB maintains a strict balance between both campuses and the placement statistics are a testament to that as no major differences can be observed.

Overall my cousin never regretted choosing Mohali over Hyderabad and recommends the same to everyone.
