Alright cool thanks a lot 😃
Your undergrad gpa is important along with your 10th and 12th gpa 'cos IIMs have a weightage for past gpas for shortlisting candidates for calls .
80% & + = good-to go
60-80% = is considered to be average, case 1 applicable.
any b-school except ISB,IIM ABCI ( unless you score a 99.7+ percentile ), little chance in other IIMs and XLRI , good to go in other great b-schools such as FMS(99.4+ recommended), NITIE(98.5+) , IITs (depends, usually 92-98.4), NMIMS, SIBM, IIFT etc.
Case 2:With an 24+ month work exp
good to go in all the b-schools with a 99.5+ percentile
@knowledgepower : A percentile of 96+ would enhance your chances of getting calls from premier institutions , just don't get stuck up over just the IIMs, good luck !!
