What is the scope of management consulting at B Schools like NMIMS, SIBM, SCMHRD and XIMB? Do non-engineers, freshers get such roles?

This would certainly not be easy for a non-engineer fresher to get management consulting roles in firms such as Accenture, McKinsey, Deloitte, EY, Capgemini etc.

• Most of the above companies provide IT consulting, operations consulting, risk consulting, etc. at these institutes. You may expect these profiles. 
• However, if you are looking for strategic consulting, then these roles are offered at only top B-schools such as IIM Ahmedabad, IIM Bangalore, IIM Calcutta, XLRI, FMS, SPJIMR Mumbai, etc. Do not expect them to be offered at the listed institutes here.

Even if some companies do offer such roles, they care about your academics in your MBA, your work experience, your personality, and your background. They want to know if you are an engineer or not, they also want to know if you know about IT or not. There are various rounds of interviews lined up to test your skills and abilities.

So, yes there will be scope especially in IT consulting roles from these institutes. All you have to do is give your best efforts and leave the rest on the companies to decide what kind of professional they want.
