I'm a chemical engineering student...
can i apply for ntpc...? Tell me the criteria to get a job in ntpc

Jobs in PSUs (Public Sector Units) is considered as one of the best jobs presently in India. The employees not only receive high remuneration and widespread facilities but also have to face less work pressure. However getting into the PSUs is very difficult since the vacancies are quite less as compared to the number of applicants. Hence one has to face good competition to get recruited in the PSUs.

NTPC is considered as one of the best PSUs of our country and is given Maharatna status because of its high turnover. In the previous years, NTPC used to conduct its own entrance test for recruitment of engineering graduates in the post of executive trainees. But now like most of the PSUs, NTPC is also recruiting engineering graduates based on their GATE score and then interview.

You have to appear for the GATE exam and score well in it. Then you need to apply for the vacancies in NTPC when the advertisement is made by NTPC. The advertisement is usually made in the leading newspapers and the official website of NTPC. Based on the received applications and the GATE scores, NTPC will shortlist candidates for the interview round. You need to qualify that followed by the medical examination and then you will get recruited in NTPC.

The syllabus for chemical engineering of GATE exam is as follows :-

improper integrals, Partial derivatives, Total derivative, Maxima and minima, Gradient, Divergence and Curl, Vector identities,
