What are my chances of getting into SIBM, SCMHRD, and SIIB?

The likelihood that you will be admitted to SIBM, SCMHRD, or SIIB depends on a number of variables, including your academic performance, work experience (if any), performance on the admission exam, and performance in the selection process (group discussion and personal interview). 

In general, entrance to SIBM and SCMHRD requires a solid profile because they are very selective business schools. A renowned B-school as well, SIIB may have a little less competition.

You should aim for a high percentile on the entrance exam (CAT or SNAP), have a strong academic record, and have relevant work experience (if applicable) to boost your chances of getting into these B-schools. Additionally, since the group discussion and personal interview rounds are so important to the selection process, it is critical to prepare effectively for both.
