Hello ,

First of all , all the the four IIM s you have mentioned are the top most B-schools in the country , but when it comes to the global ranking IIIM -A comes at top among the four with 46th rank , after that at slightly lower rank comes the IIM Bangalore with 50th rank , then comes IIM Calcutta with 79th rank , and at last is the IIM Indore whose rank is between 151-200 ranking , so overall all the four IIMs comes under the top 200 global rankings , and if we go placement wise then all the four IIMs have the best packages all over the country ,

I am sharing you a link for all the IIMs of career 360 , from which you can know about the courses , placements , facilities , reviews, and much more :
