IIM Ranchi has Sectional as well as Overall cutoff. The cutoff for 1st Stage of Shortlisting is decided by the Candidate’s Valid Scores in the CAT Examination. While for the Final Selection, CAT Percentile, Performance in Personal Interviews followed by Academic & Gender Diversity is considered.
There is a huge weightage on work experience. This is because I have seen instances where freshers were rejected despite a 99 percentile while people with experience of 2-3 years were selected despite 90-93 percentile.
