As an admit to IIM-C PGPex I can only provide my suggestion regarding IIM-C PGPex , however that should apply to any other IIMs if you wish to apply . So here goes my experience.
1) Since PGPex caters to experienced professionals and needs atleast 5 years of work experience as part of it's eligibility criteria therefore the adcoms look beyond your acads and GMAT scores. However, a good GMAT score , which is nearer to the school's avaerage which is currently 705 , would obviously enhance your chances for a shortlist. So, get in an get a decent GMAT score. Don't get too obsessive about the scores though.
2) As part of the application process there would be a SOP and essays to write. However, if you introspect and try to get answers primarily to these three questions then I believe any such essay will not pose a problem . The questions would be : Who are you a.k.a tell me something about yourself, What do you want a.k.a your short-term and long-term goals and How you wish to realize your goals a.k.a Why an MBA?
3) Since the pool of applicants are super competitive therefore during the interviews confidence and calmness plays a very important role. Trust me , a 10 min conversation is all the adcoms need to guage your suitability for the course so if you are confident and calm you might even end up not getting bamboozled with tangent questions such as what is the cube root of one or what is a reverse repo rate?
4) Having said that, i would also suggest to start reading as much as you can , about the course and the happenings around the world. It helps your confidence and arguments during the interview. For the notorious parts of the interview, do touch-base upon basic math and statistics as IIMs are known to ask such questions. I personally feel that such questions are asked to take you off-guard while the adcom observes how you react and recover from that situation , so keeping calm is very important.
Hope this helps. If you have any other queries please do ask them and we will be happy to help.. Good luck!!
