It is recommended not to join any of the 2 mentioned colleges, neither DoMS, IIT Madras nor IIM Amritsar, as the placements at newer Indian Institutes of Management (IIMs) are not yet on par with top colleges. Placements at newer IIMs are still evolving and it may take at least a decade for them to stabilize and for the demand for MBA degrees to increase in the long run.
It is important to note that Indian Institutes of Technology (IITs) are not generally considered to be top colleges for MBA programs, although IIT KGP and IIT Bombay have made a name for themselves. These institutions are primarily known for their strong focus on technology. If you are considering top MBA programs, IIT Madras is a good option due to its brand recall.
The institution has the potential to attract top tech companies to offer MBA roles as well. Older IITs have a well-established reputation which newer institutes may not yet have. It took almost 3 decades for IIM Lucknow to reach its current level of prestige, and that was without the level of competition that newer IIMs face in attracting the best companies and roles on campus.
