Hello Aditya

As per the previous year's cutoff, chances are less for getting a call for admission to the MBA programme in  SIBM Pune. You might get a call from any other other institutes. However, it should be noted that the selection process includes Group Discussion, Written Ability test and Personal Interaction Rounds.
Admission is done on the basis of performance in the SNAP exam, selection rounds and candidate's profile is also considered. 

So, you need to have overall a strong profile for selection. You can go through the link below and check the previous year cutoff details and the expected cutoff for reference.
