Dear aspirant !

Hope you are doing well! As far as I think isro prefer to go with mechanical engineers rather than mettalurgicals ,also they hire metallurgical alternative years once ,vacancy for metallurgical is too less might be 1 or 2 every year ,this year no chances ,hope vacancy will be come next year in 2023 ,but also other than drdo and isro ,a lot of opportunities are there in other fields .

Hope it might get idea !

Thanking you !
