Hey there!

You are eligible for all the IIMs as long as you clear the examination. The examination called CAT is what you'll have to appear for if you want to get into the IIMs. The admission would be divided into two parts, firstly you'll appear for the examination and if you get a good percentile you'll be called for the interview for the particular IIMs. Along with the interview there will be a group discussion as well. If you clear all of this then you'll get into an IIM.
