I scored 93 marks in slot 3. I am non- engineer with 89/88/89 in 10th 12th and Grad from EWS category. Any chance of getting calls from decent IIMS

start preparing for interviews

Well, if you are an Arts grad, then you would surely get an interview call from even IIM Ahmedabad. Of course, you would get an interview call from IIM L, K and all the new IIMs.
