Hi Priyanshu !

DRDO recruits engineers through the following :

1)Through Gate/NET

2)Through apprenticeship

3)Through their own exam sometimes

4)Through direct interview for contract basis.

Every year RAC of DRDO recruits Scientists in DRDS mostly at entry level (Scientist 'B'). However, depending on the requirements in specialized areas of research & development, limited number of scientists are also recruited in higher grades (Scientist 'C' to Scientist 'H').

Qualifying GATE is mandatory eligibility for Recruitment in DRDO. Other than that, candidates also have to appear for a written descriptive test followed by a personal interview as a part of DRDO recruitment through the GATE 2021 procedure. Candidates will be allowed to work for DRDO only after qualifying for all the stages.

The elgibility criteria goes like this:

Essential Qualifications

1. At least first class Master's Degree in Science Subjects, Mathematics or Psychology or First Class Bachelor's Degree in Engineering or Technology or Metallurgy from a recognised University or equivalent.
2. Experience of at least 3 years for Scientist 'C', 7 years for Scientist 'D', 10 years for Scientist 'E', 13 years for Scientist 'F' and 15 years for Scientist 'G'/Scientist 'H' in research/ design/ development or production in the required area.

Desirable qualifications

1. Knowledge of Chinese, French, German, Japanese or Russian
2. Doctorate degree in Science, Mathematics or Psychology or Master's degree in Engineering or Technology or Metallurgy in the subject concerned (applicable for Scientist 'C' & above).
