Untitled-1This is the one of the recruitment service in india to recruit students/persons from four engineering department(electronics and telecommunication, mechanical, electrical,and civil engineering) in government sectors.This is the one challenging and good job to the person who looking for higher post(grade-A & grade-B) in government engineering sectors.They releases a notification every year in the month of Feb/march endings we can also check the notification detail in UPSC calendar in the upsc website( www.upsc.gov.in).
Various government posts present in electronics and tele-communication department(Group-A & Group-B) are:
  1. Indian railway service of signalling engineers.
  2. Indian railway store service.
  3. Indian naval armament service.
  4. Assistant execuitive engineer Group-A in the corps of E.M.E, ministry of defence.

  11. Junior telecom Officer(Group-B Gazetted)
  12. Central Power Engineering services Gr-B
Now to get in to these post first you must Qualify written Exam and Interview, Written Exam consists of  five papers and the exam will conduct on 3 days.
paper-1 General studies
Paper-2 Objective technical(6 subjects)
Paper-3 Objective technical(6 subjects)
Paper-4 Descriptive technical(6 subjects)
