if i apply for CAT in final year of my graduation then in that case i have 0 work experience.Will i get the call from IIM or not..??

You can definitely get a call from IIMs and other top colleges being a fresher also but you'll just have to score 95-100 percentile in CAT and will have to have a good past academic record. But don't run only after IIMs. Even if you manage to get 80 percentile you'll land on to a good college and ultimately a good job and while on the job it doesn't matter which college you've studied from.

All the very best

Hello greetings

Every IIM has different weight to the work experience and it is also considered weather the quality of work is relevant for other management studies or not so in general there is roughly 5 to 10 marks at Max for work experience out of hundred and every other IIM has its own different selection process therefore even without having work experience there are chances that you get a call from IIM if you score well in the CAT exam and also have good profile in class 10th and 12th.
