My brother was a student at this college and so this answer is based on his experience solely. The Department of Financial Studies is a CFA-affiliated college wherein you can get a scholarship for pursuing a CFA degree. Its MBA program is highly coveted. It's the best option for you if you want to pursue a career in Finance and fail to make it to other B Schools. Here are some factors to consider 

• Fees: The low fees charged by DFS is the USP of the college. You can pursue an MBA at just 26000. IIMs fees on the other end are very high Around 13–24 lakhs. So DFS offers a better ROI than IIMs.
• Curriculum: Curriculum-wise, DFS cannot be compared to IIMs that have excellent course structure at par with foreign universities. DFS follows the semester pattern, unlike the trimester pattern in IIMs. IIMs conduct case study competitions but this is not the case at DFS.
• Faculty : DFS has some very well-educated and experienced faculty members much better than at least the new IIMs.
• Placement: The placements at DFS are at par with new IIMs only and not other top IIMs. 
• Alumni: The small batch size of DFS has failed to establish an elaborate alumni base in contrast to IIM Ahmedabad.

Ultimately, if you don’t want a huge loan to repay at the end of 2 years or the IIM tag, DFS is the best option

Both the options you mentioned, IMI Delhi PGDM and IMT G Finance are good in their own individual aspects. So you should rather be asking which is better for you. Now this depends on what you really want from your PGDM. By choosing PGDM Finance you will limit yourself only to the Finance sector, whereas a PGDM core will give you a chance to explore various domains before selecting your specialization. The former is a good option if you are certain about your interest in Finance and want to excel in that sector no matter what while the latter is good if you are open to all options.

Talking about IMI Delhi in general, the B School offers an abundance of opportunities through student bodies and other student driven activities. Moreover the additional locational advantage is what makes it a fairly good option. The batch size is also not too big and thus balances the student teacher ratio.

Placements are pretty decent at IMI Delhi. The IMI Delhi average package (overall) offered during 2023 placements was INR 17.01 LPA. For PGDM, PGDM (B&FS), and PGDM (HR) the average package stood at INR 17.20 LPA, INR 16.48 LPA, and INR 15.58 LPA, respectively.

The primary highlight of the B School is its student exchange program wherein students from foreign universities join the B School for a fixed period while students from IMI Delhi visit a foreign university in exchange.

All these factors make IMI Delhi a very good choice in comparison to IMT G.

ISB Hyderabad is known for its lack of specialization in Finance. It’s a common understanding now that even if one is preferring ISB Hyderabad for admission, they know that they should go for anything but Finance. Studying some aspects will give you a deeper insight as to why MBA in Finance from ISB Hyderabad is not recommended.

Faculty: Although the visiting faculty is quite decent, it’s the domestic faculty that has ruined the culture at ISB. They are arrogant, pathetic, and extremely incapable. They insult the students regularly and disturb student-teacher relations.

Placements: The roles offered in Finance were below average like Operations, Sales, and BD roles. Such roles were offered in abundance by the banks or start-ups. However, the superior roles like IB/PE/VC/M&A/FP&A/Equity Research/Credit Rating/Asset Management/TAS were offered scarcely. For instance 

• only 10 FP and A roles were allotted that too only to CAs
• Only one Investment banking role was offered by Barclays
• Only 5 PE/bc roles were offered and there was a strong preference for a prior IB/PE/VC experience and IIT undergraduate background.
• One M and A role was offered only
• 4 Asset Management and zero Equity Research and Credit Rating roles were offered.

So the best roles were offered limitedly while the batch size stood at 900. Most students ended up with unsatisfactory placements. Now you can decide whether or not to join if you are confident to face the placement scenario.
