Why are IIMs more popular than ISB Hyderabad among Indian households?

There are many major reasons why ISB Hyderabad is not as popular as IIMs among Indian households. Some of them include 

• ISB Hyderabad is a private non-AICTE affiliated institute that functions under a totally different model.
• Owing to its hefty fees(around 30+ Lakhs), it's almost inaccessible to an average Indian.
• The batch size is huge becoming a major obstacle during placements 
• The 1-year program fails to provide in-depth exposure and is just a source of Certificates and a brand tag.
• It does not provide International placements to the majority of students who do not belong to the elite class.

All these reasons are strong enough to persuade one against joining ISB Hyderabad and is thus not much popular among Indian households.

The reason why IIMs are popular in contrast to ISB Hyderabad are

• Provided jobs similar in nature to the ones provided by ISB Hyderabad at a much lower fees.
• The 2 year MBA program provides an in-depth exposure to the curriculum in contrast to the 1 year program at ISB Hyderabad 

So all this makes IIMs much popular in India despite ISB Hyderabad global rankings.
