Hello candidate,
The CAT cutoff for General category for most of the IIMs is 90+ percentile. To get shortlisted for the selection rounds, you need to meet the CAT cutoff criteria. Shortlisted candidates are called for the selection rounds which usually include a Writing Ability Test (WAT), Personal Interview (PI) and Group Discussion(GD). Apart from this, some other parameters are also considered such as Work Experience, Past Academic Records, Diversity, etc. to prepare the final merit list for admissions.
