Ever wondered what brought you into IIMB? This might be close to the criterion used in our times -
The results of X and XII standard of a candidate accounts for 25 per cent of the score, while the bachelor’s degree accounts for 15 per cent. Maximum weightage of 35 per cent is given to group discussion, group discussion summary and personal interview, while the remaining 5 per cent is for work experience and whether the candidate has taken any other professional course like accountancy.
To be called for the interview round, a candidate should be in the top 15 per cent scorers in each section of the CAT. Candidates belonging to the Scheduled Castes and Scheduled Tribes and disabled applicants need to be in the top 50 per cent in the logic and quantitative sections and top 45 per cent in verbal section.
