MDI will be a better option for all specializations, except Operations. If you are interested in Operations, IIT Bombay is much better. MDI Gurgaon placements are excellent. Big names such as Bill & Melinda Gates Foundation, and BCG have visited the campus placements. The 2022 placement drive had an average CTC of INR 26.65 LPA. 

MDI offers the best placement in the finance domain after IIM A, B, C, FMS, and XLRI. JP, HSBC, Nomura, Stanchart, etc. are some of the major recruiters from the finance sector. 

MDI placement records for Marketing are good as well. HUL, Coke, Pepsi, and P&G are some significant recruiters from the marketing sector. 

My cousin recently graduated from SJMSOM and has begun working at Fidelity Investments as a Delivery Manager for almost 3 years now. He suggests going for SJMSOM only if, 

• You essentially prefer studying amidst a comparably smaller batch size.
• You further want to be at the Financial Capital, for either internships or job purposes.
• You prefer going for the best infrastructure and basic amenities.
• You can enjoy the brand value likewise.

You can opt for IIM Indore only if you prefer the following,

• You are confident that you can compete and stand out with a larger batch. 
• You will receive the major brand value that comes along with IIMs.
• You want to secure a seat at one of the best management institutes.
• However, the placements of either institute are somewhat similar, with relevant recruiters visiting both campuses occasionally during placement seasons.
• Both the institutes offer exchange opportunities as per schedule.

Here is a brief overview of both SJMSOM and IIM Indore. 

Both institutes are reputed so take a call based on your personal preference.
