As far as I know having work exp is considered as a positive point but not having it is NEVER a negative point.
This is because every institute in India wants to have a fair mix of work-ex n freshers or boys n gals or different academic backgrounds to have a diverse and learning culture in the organization. This helps in peer to peer learning across collegues.
So do not worry. Unless u r applying for ISB, Hyderabad, not having work-ex is not going to be against u.
Just do ur best. And have convincing justifications for all ur career moves like moving between jobs or leaving job.
That's it.
What is more imp than brooding over work-ex issue is working towards preparing ur best for the Test.
I know a guy fresh BE, went to IIM L interview while having 7 ATKTs and having abt 48% aggregate percentage in first 3 yrs of engineering.
But ppl HE IS IN!!!
He got selected there in IIM L. All thanks to his dynamic, well read n very confident personality. And very important his percentile in CAT 99.90%.
HATS OFF to HIM!!!
All the best to all freshies!!! Do not worry do ur best.
