For the Human Resource Management program, the overall cut-off for male engineering applicants is 93 percentile, while it is 91 percentile for female engineering students.
Male applicants with non-engineering backgrounds must have a 90 percentile, while female applicants with non-engineering backgrounds must have an 88 percentile. It's possible that even with a high percentile, you might not be chosen if you have a poor interview performance.
While it's helpful to have some sense of scale, I'd advise shooting for the stars and ignoring percentiles for the time being.
