Dear Kumar, Coal India recruitment is totally uncertain. We can't predict any move by the company. Second last time he has recruited in 2011 and 2012, after two consecutive recruitment, company didn't recruit till 2015. After that it recruited in 2018. It is predicted that many old age employee are getting retired in coming year so company will certainly face employee (executives) scarcity. I can't say any thing from above statistics but I only advice you to keep studying and try other companies till CIL next recruitment.

All the best

Hope this helps
