The chances of getting an interview call from SIIB, or SIBM Bangalore with a SNAP score of 87.6 are very less. Below are the cutoff details, for these institutes.
SIIB Pune cutoff - 93
SIBM Bangalore cutoff - 90
Naturally, the required cutoff changes each year depending on various factors, such as competition, the difficulty level of the examination, etc.
You might receive an interview call from Symbiosis Institute of International Business (SIIB) only if there is not a noticeable change in the cut-off percentile.
However, SIBM - B is known to have a cut-off of 88 percentile for the general category. If they have decided not to bring any update or change in the cut-off percentile, then your chances of receiving an interview call are slightly less.
It is suggested that you wait since SNAP is going to be online, and that might result in changes in the cut-off percentile. Thus, before deciding further, you will need to wait until the cut-off list releases.
Although, the cut-off of last year of the SNAP test for all the specializations was 92 in SIIB, Pune.
