Two candidates, identical percentile, completely different call sets. The reason is published in a PDF almost nobody reads until January.
Most IIMs do not shortlist on CAT percentile. They build a composite score that weighs the CAT percentile alongside Class 10 marks, Class 12 marks, graduation performance, work experience, and academic and gender diversity. The weights differ by institute and are published before shortlists go out. That is why two candidates with an identical percentile routinely receive completely different sets of calls — and why the most useful twenty minutes you can spend in December is reading five criteria documents.
Every institute publishes its own selection criteria, and they change between cycles. The ranges below describe the pattern across institutes — they are not a substitute for your target institute's own published document. Read those in December, before results.
The largest single component at most institutes, but rarely a majority on its own. Sectional minimums apply underneath it as a hard gate.
Carry real weight at several institutes. Entirely fixed — nothing you do now changes them. Worth knowing rather than worrying about.
Usually weighted, sometimes normalised by discipline because grading differs sharply between streams.
Rises then flattens, typically peaking around two to three years. Beyond that it can plateau or count against you.
Engineers are heavily over-represented in the applicant pool, so non-engineering backgrounds are generally scored higher here.
Most institutes award points to improve batch balance.
Take two candidates at the same percentile. One has strong Class 10 and 12 marks, a non-engineering degree and two years of work experience. The other has an average school record, an engineering degree and no experience. At an institute weighting academics and diversity heavily, those two are not close — and neither of them could have known that from the percentile alone.
This is the single most common source of January disappointment, and it is entirely predictable in December. You can run the arithmetic on your own profile with the composite score calculator — put in your target institute's published weights rather than the illustrative defaults, and the number becomes meaningful.
A call is permission to be assessed, not an offer. At the final stage most institutes re-weight everything, and the CAT score usually counts for substantially less than it did at shortlisting — often somewhere between a quarter and a third, with the interview rounds carrying a comparable or larger share.
Which means a candidate who scraped a call can convert ahead of one who sailed in. WAT-PI preparation is where that gets decided, and the whole sequence is laid out in what happens after CAT 2026.
Most build a composite score rather than ranking on CAT percentile alone. The composite typically weighs the CAT score alongside Class 10 marks, Class 12 marks, graduation performance, work experience, and academic and gender diversity. Each institute publishes its own weights, and they differ substantially.
Almost always the composite score. Class 10 and 12 marks carry real weight at several institutes and cannot be changed, academic diversity favours non-engineering backgrounds because engineers are over-represented in the pool, and work experience is rewarded only up to a point. A strong percentile with a weak academic record can score below a lower percentile with a stronger one.
Up to a point. Most institutes reward experience on a rising scale that flattens after roughly two to three years, and some score it down beyond a certain level. More experience is not linearly better, and freshers are not excluded - several institutes reserve substantial intake for them.
Shortlists typically come out from early January through early February, after the CAT result in late December. Each institute runs its own timeline and publishes its own list, so calls arrive over several weeks rather than all at once.
