I finished my B.E and I am working in accenture with 3.5LPA. LI want to do MBA in IIMS.

Hi, There is no minimum work experience requirement for IIMS. Every year, a lot of fresher's also make it to IIMS. It is mainly the weightage on the CAT score. You might get preference on Work Experience. For Example - here is the selection criteria for IIM Bangalore for 2018: IIM Bangalore Overall

Hello, They conduct an entrance aptitude test. You need to give that. There is no such work experience criteria for admission I am afraid. All the best.
