Hi Chandan,

As I can see here, the forms for IOCL recruitment are not out yet and are scheduled to be made available is a few days. The last date for application is not announced till yet either. And same goes in the case of BHEL. 

However, the forms are expected to be out soon and before February end, the links of both the forms will be made available on our portal as and when they are released. 

You can go through the following links to know more about the application dates, requirements and eligibility.

I hope this will be useful.
