Can I get admission? I have a very low score in CAT, and have 18months of experience in an MNC in relevant field.

CAT cutoff is fixated, irrespective of your work experience. So in the merit category, you may not get the call. But there is something called NRI category, wherein you might get a call, but you will have to pay more fees. Kindly go through the Information Bulletin, that is available on the websit
