Percentile required for blacki calls

With an 86/88/71 profile, SC category, male, engineering background, and a 2-year gap, your profile is fairly decent, with the SC category being a significant advantage for IIM shortlisting.

For BLACKI, around 97+ percentile, with 96.5+ giving you a strong target for the MBA colleges. You should still aim as high as possible because the actual shortlist depends on each IIM's composite score, academics and sectional performance; for example, IIM Ahmedabad's current SC minimum is 85 overall, but the actual shortlist is based on a composite score rather than the cutoff alone.

The 2-year gap shouldn't be a major concern if you can clearly explain what you were doing during that period. Overall, I'd set 96.5+ as the target, while 97+ would put you in a very strong position across BLACKI.
