hi,

see isro is an renowned indian space research organization, isro hires al most every year for scientist b positions and scientific assistant post, also diploma level, ITI trained workers vacancy also come, however for scientist b role, btech graduates or mtech graduate are allowed to apply as far last notifications, however due to corona pandemic and economic crisis there is chances that this year there may be less number of recruitment, I suggest you to look over their official website for upcoming recruitment.
