Many of my students attend IIM programs in Shillong, Ranchi, and Raipur each year. While the placement outcomes at IIM Shillong and Ranchi are similar, the campus at IIM Shillong is more attractive and students at IIM Ranchi must spend an hour commuting to classes every day.
Additionally, the lack of a campus at IIM Ranchi may limit the ability to participate in a vibrant social scene. Therefore, IIM Shillong may be a better choice for those who value the campus learning experience.
