they are gonna conduct exam every month for sure but as they reached the saturation level, they r planning to take very few from oct attempt.
thank you for the information about the next attempt, I really appreciate that but I wish to disagree with you on the 'saturation level' due to the following reasons:
IndiGo has a very big order pending- out of the 100 a/cs ordered only 43 have been delivered till now and then there is the 180 a/c order(I do not know if they have finalized it, or it is still a MoU)
Secondly it takes about 8-12 months for a cpl holder to go online- i think an airline like indigo, who had the paperwork ready a year before they were supposed to go international would not want to train their pilots after getting the deliveries.
But that is my own perspective, i could also be wrong about it. I know everyone has their own opinion about things, and I respect yours. Good luck to everyone for the next attempt.
