In case you are enquiring about the CAT percentile let me clarify that ISB Hyderabad does not take into consideration CAT scores. It accepts GMAT/GRE scores only. Most importantly, the ISB Shortlisting process is profile-based. This means even with a lower percentile you can manage to get shortlisted provided you have an excellent profile.
There is no fixed cutoff for GMAT. However, a 700+ GMAT score isn't a must-have for ISB if your application is strong in other areas. According to an ISB spokesperson, candidates were admitted to the 2021 cohort with scores as low as 580, and as high as 780. So the GMAT score range for ISB is 580-780.
