DRDO Scientist/Engineer Examination — Eligibility, Syllabus & Exam Pattern

DRDO Scientist/Engineer Examination — Eligibility, Syllabus & Exam Pattern

The Defence Research and Development Organisation (DRDO) recruits bright and qualified candidates for the post of Scientist 'B', one of the most prestigious technical positions in the country's defence research sector. The primary mode of recruitment is through GATE scores, but occasionally, DRDO also conducts its own separate Written Examination. In both cases, shortlisted candidates are called for a final, decisive Personal Interview.

📌 Eligibility Criteria

Nationality

A candidate must be a citizen of India.

Age Limit

The upper age limit is 28 years for the General category. Age relaxation is available for reserved categories (OBC - 31 years, SC/ST - 33 years) as per government rules.

Educational Qualification

A candidate must have a First Class Bachelor's Degree (B.E./B.Tech) in a relevant engineering discipline from a recognized university. The required disciplines commonly include:

  • Electronics & Communication Engineering
  • Mechanical Engineering
  • Computer Science & Engineering
  • Electrical Engineering
  • Aeronautical Engineering
  • Chemical Engineering
  • Civil Engineering

✍️ Selection Process & Syllabus

DRDO recruits Scientist 'B' posts through two main channels.

1. Recruitment Based on GATE Score (Primary Method)

This is the most common method of recruitment. Candidates are shortlisted for a personal interview directly based on their valid GATE scores in the relevant subject paper.

2. Recruitment Based on a Written Examination

Less frequently, DRDO conducts its own written examination. The process is as follows:

  • Written Exam: The exam consists of two objective-type papers conducted on the same day.
    • Screening Test: A qualifying paper that candidates must clear.
    • Selection Test: A paper in the specific engineering discipline. Performance in this paper determines shortlisting for the interview.
  • Personal Interview: Shortlisted candidates are called for a final interview.
Syllabus for Written Exam

The syllabus for the written exam is not rigidly defined but is based on the standard curriculum of the B.E./B.Tech degree in the respective discipline. It is generally aligned with the GATE syllabus for that engineering branch, focusing on core technical subjects.

👉 Note

  • The final selection for DRDO Scientist 'B' is typically based on the performance in the Personal Interview, with the GATE score or written test being used for shortlisting.
