DRDO Syllabus - Chemical Engineering

Important Notice - DRDO Scientist recruitment via GATE Score

Requirement of Valid GATE Score for Direct Recruitment of Scientist `B’ in DRDO Be it known to the candidates desirous of recruitment to the post of Scientist `B’ in the Defence Research & Development Organisation that the organisation would be notifying vacancies of Scientist `B’ for the year 2018 in the next few months, depending upon the requirement. The direct recruitment to the post of Scientist `B’ will be conducted based on valid GATE (Graduate Aptitude Test in Engineering) score (in respect of vacancies in the subjects/disciplines for which GATE is conducted) and interview. Only those candidates who will have valid GATE score on the crucial date of eligibility will be considered for shortlisting for recruitment.
