It is really tough time for the job - seekers and as a result we can see even the overqualified candidates such as Engineering - graduates, MBA's, post graduate degree holders in different subjects make beeline even for the clerical jobs. So, in order to secure the job even for the clerical nature, you need a thorough preparation in that line. You need to face both written and oral test and final selection would be made on the combined performance of these tests. This requires a specialised coaching from some reputed institute to clear the tests under their guidance.
However, it would be better to defer the immediate gain by a way of getting a job at this stage and think for better future by taking up your further studies for the graduation. This will open up new avenues in numerous jobs such as Probationary Officers jobs in both Nationlised and Private Banks, Probationary - officers of LIC, Continuation of MBA through some prestigious Institute or even you can persue MCA for getting job - assignment in IT sectors.
If interested for teaching in Higher Secondary Schools, you can persue B. Ed degree or still better achieve the post graduate degree of your liking with at least 55 percent marks and clear the eligibility test for the Lecturership in a government - college.
Even you can try for IAS, if you have a passion for this through your hard labour after your graduation.
