This answer is based on the experience of a friend who completed her MBA from MDI Murshidabad. The points of comparison between MDI Gurgaon and MDI Murshidabad are mentioned below

• The curriculum is almost similar to the pedagogy adopted is also very similar 
• Most of the faculty is from MDI Gurgaon, IIM Calcutta, IIM Shillong, and other prominent B Schools
• The infrastructure and facilities are decent enough to meet the requirements of a B School.
• The institute provides a decent digital base that has major databases that helps in conducting basic research related to industry and academics. Yet this library is not as fast as MDI Gurgaon.
• Comparing the placements is not justifiable as the duration of establishment is highly varied. But a general view ensures that MDI Murshidabad is going as per the trends in the industry.
• Many national and international companies approached MDI Murshidabad students with decent job offers.

Be it a B School of the MDI family or the IIM family, it’s your efforts that enable you to get successful. Being serious about learning and having the desire to do better helps develop a better business sense which is in dearth these days.
