Hey Preet

Selection in Indian Institute of Management (IIM) is not dependent on Academic   profile only, but on:

• CAT score
• Interview + WAT Performance
• Work Experience
• Gender Diversity
• Curriculars
• Academics

One cannot predict selection so accurately but 8 years experience might compensate other factors and you should aim for a much higher percentile, 98-99 for increasing your chances, and perform good in Interview round. Giving best in all rounds and maintaining good profile will definitely increase chances of selection in any IIM.
