In any government sector, there will always be a process of getting job which constitute Entrance test and interviews.
I am not sure for which government sector you are talking about but in any sector you have to be eligible according to the conditions mentioned for birth date, educational qualification and your various other parameters should suit to the post you are applying for.
Please be sure to check eligibility condition before applying to any job as most of the cases are that incomplete and ineligible candidates waste there money on forms and got rejected.
so check the eligibility condition and apply for the post.
Best of luck for you future.
