When considering the three business schools in question, IIM Sambalpur, IIM Sirmaur, and IMI Delhi are in the same league, with IMI Delhi having a slight edge over the other two in terms of placements. This is due to the fact that it is older than the newer IIMs and has been in the B-Schools scene for a longer period of time. However, it is important to note that the newer IIMs have had a meteoric rise because of their IIM designation.

All three of these business schools are good in their respective positions, but if you have a slight preference for Human Resources, IMI Delhi may be the better choice for you due to the HR profiles offered to students and the school's reputation for its HRM program. Additionally, while the location of IMI may be more favorable, if you are looking to study and make the most of your next two years in a more secluded setting away from the hustle and bustle of a metro area, IIM Sirmaur or Sambalpur may be more fitting.

Ultimately, it is important to reach out to students and alumni of these respective business schools to gain a clearer understanding and make a decision that aligns with your own preferences and goals. It is important to remember that ultimately, the decision should be based on what will allow you to perform at your best.
