It depends on the percentile you score in the examination which is a relative method. It seems tough to get a call from old IIMs but you can expect a call from New IIMs if you score more than 96 percentile. Baby IIMs can roll out calls at a percentile lesser than 96 depending on their batch size and admission strategy. You can expect a call from them if you score above 90 percentile.

All the best!
