The opening of ISM Dhanbad is a testament to the increasing demand for an MBA from IITs. Apart from ISM and IIT Delhi, IIT Madras also provides MBA programs to students from various domains. The minimum percentile required for admission to the IIT Madras is different for each category. An estimated CAT percentile for IIT Madras is
96-99 for General Category
93-95 for NC-OBC Category

My friend shared his MBA interview experience at IIT Madras wherein the panelists advised him to go for IIMs if he was inclined toward Marketing as IITs specialize in Operations only. Decide after proper research only.
