For Entry to Govt or public sector jobs, a list of eligible Engineering qualifications is indicated. For e.g. a particular job may have an eligibility criteria of Engg in C.Sc, ECE, Electrical. Whereas other job notifications may consider any Engg degree as the eligibility criteria. There may not be jobs specifically and restricted only to C.Sc. Engg graduates are also eligible to apply for Govt jobs that specify any graduation as the eligibility.
There are numerous openings in State Govt jobs, Central Govt jobs and Public Sector for Engg graduates including Computer Science. Like UPSC, IES, Railways, NTPC, Defence (DRDO etc), GAIL, SAIL, Telecom/BSNL, State Electricity generation and transimission depts, Irrigation depts, etc.
