Hello Rahul,

Yes Rahul you're right according to the Advertisement it says that the application link will start by 4th of January on the link available on www.iocl.com , but from few days the link is not available. The advertisement also says that you have to apply once you get your Admit Card . So, there are chances that the link will open after that.

Also, the official website states that the link will be available in few days keep checking the site I am giving you a link where you can directly check the details
