For a GEM (General, Engineer, Male) candidate with 98.18 percentile in CAT 2025 and an excellent academic profile of 10/9/8, your chances of receiving calls from several top-tier MBA institutes are strong, though being a GEM candidate does make the competition more intense. At this percentile, you can reasonably expect calls from IIM Shillong, IIM Udaipur, IIM Trichy, IIM Raipur, IIM Ranchi, IIM Kashipur, IIM Rohtak, and IIM Nagpur, provided your sectional percentiles also clear their minimum cut-offs. Among the older IIMs, IIM Indore and IIM Kozhikode may be borderline to possible, depending on how your academic diversity score, graduation discipline weightage, and work experience align with their selection criteria. Calls from IIM Ahmedabad, Bangalore, and Calcutta are unlikely for a GEM candidate below 99.5 percentile, even with strong academics. Apart from IIMs, you have very good chances at MDI Gurgaon, SPJIMR (profile-based calls), IIT Bombay (SJMSOM), IIT Delhi (DMS), IIT Madras (DoMS), IIT Kharagpur (VGSoM), and IIFT (if applied). Final conversion will depend heavily on WAT–PI performance, so focused interview preparation is crucial.
