IMI Delhi is better than IIM Sirmaur. It is a reputed and older b-school. IMI brand name is well-recognized in the industry. It has a rigorous pedagogy and a brilliant faculty base. Being located in Delhi, students get good exposure to the industry nearby. 

IMI Delhi placements are excellent. According to the highlights of 2022, students received an average CTC of INR 15.23 LPA. While the highest CTC offered this year was INR 32 LPA. HDFC Life, Capgemini, BCG, Deloitte, etc. are among the top recruiters that take part in the campus drive. 

After scrutinizing the list of colleges you mentioned, I think the most viable option is IIM Bodh Gaya. It is the most suitable among the 3 because it has been growing at a spectacular rate. The 2 major reasons for its rapid growth are

• Location: IIM Bodh Gaya enjoys a location advantage due to being situated at a Buddhist tourist spot. The historic pilgrimage site is well connected with an airport just 7 km away. Six connectivity brings in better and more faculty and also top companies for recruitment that don’t visit Sirmaur and Sambalpur due to poor connectivity.
• Mentorship: This is another factor that sets IIM Bodh Gaya apart from other baby items. Once under the mentorship of the top IIM, IIM Calcutta, IIM Bodh Gaya still has a similar pedagogy and curriculum.

Both these factors differentiate Bodh Gaya from Sambalpur and Sirmaur extremely well.

You should join IMT Ghaziabad. It is a reputed management institute with a decent placement record. IMT has an excellent faculty base, especially for marketing. Professors are friendly and cooperative. The institute has many clubs and committees, that you can take part in. The highest and average CTC offered during IMT Ghaziabad placements 2022 were INR 15.28 LPA and INR 62 LPA, respectively.  

Compare the summer and final placement reports of both batches for all the 3 years. Look up the student clubs and activities on both campuses. They are absolutely necessary for your 2 years there. Finally, look up the professors in both colleges, majorly for the subject, you will probably be specializing in. Good professors impart their experience along with education. Keep in mind that IIM Bodhgaya, however, lags behind in one vital factor i.e., the number of students. In all probability, the students in the upcoming batch (your would-be batch) in Sirmaur will be more than if you were in Bodhgaya. A healthy amount of interaction matters a lot, especially because it's a business school and you benefit from the range of ideas numbers can provide. 

However, the final decision is up to you entirely. Assign weights to the above factors and decide accordingly. After taking the decision, do not second guess your choice after going into one of the colleges. Make the best of your time there. Chase excellence in every facet of your MBA while you are there. If you do this, the choice part will cease to matter in a few months.

Yes, personally I think if you have the above options only, then definitely go for IIM Bodh Gaya. The institute has many perks that will not leave you regretting your decision.

• Single occupancy hostel room
• 24 hours power backup

• A gym
• A common room to watch TV and play table tennis
• Facilities for outdoor games like volleyball, badminton, football, cricket, basketball are also available.

All these advantages make IIM Bodh Gaya a better choice.
