Eligibility & Age Limit
Age Limit: —–28 years as on Date specified in the notification — typically last date of application
OBC: +3 years; SC/ST: +5 years; PwBD: +10 years (UR), +13 years (OBC), +15 years (SC/ST). Departmental candidates with 3+ years' DRDO service get +5 years.
Educational Qualification:
- Engineering disciplines (CoT route): B.E./B.Tech in the relevant engineering discipline with first class (minimum 60% aggregate, or CGPA 6.75 / 10) — Electronics & Communication, Mechanical, Computer Science, Aeronautical, Civil, Electrical, Metallurgy, Chemical and allied branches as specified in the cycle notification.
- GATE-route alternative: A valid GATE score in the relevant discipline with the cut-off declared by RAC for the cycle. GATE score validity is typically 3 years.
- Specialised disciplines (tabulation): Master's degree (M.Sc / M.Tech / M.E) in the specialised area (materials, aerospace, life sciences) with first class — direct interview without written test.
Nationality: Indian citizens only.

Frequently Asked Questions
Who is eligible for DRDO Scientist B posts?
B.E./B.Tech graduates in Electronics, Mechanical, Computer Science, Aeronautical, Civil, Electrical, Metallurgy or Chemical engineering with first class (60% aggregate or CGPA 6.75/10) are eligible for the engineering-discipline route. M.Sc/M.Tech postgraduates in materials science, aerospace, life sciences and other specialised areas can apply via the tabulation route — direct interview without written test.
Does DRDO accept GATE scores?
Yes. DRDO RAC accepts a valid GATE score (typically last 3 years) as an alternative to the Centralised Online Test (CoT) for engineering-discipline Scientist B posts. The cut-off varies by discipline and cycle. Candidates can choose either route — GATE-route applicants are merged into the same merit list as CoT applicants for interview shortlisting.
How does DRDO RAC differ from ISRO Scientist recruitment?
Both recruit B.E./B.Tech graduates at Pay Level 10 entry-level, but DRDO has broader discipline coverage (50+ labs across Aeronautical, Naval, Missiles, Electronics Warfare, Life Sciences) versus ISRO's focus on aerospace systems. DRDO accepts GATE scores; ISRO conducts its own descriptive written test. DRDO has more vacancies per cycle (200–300 vs ISRO's 60–110). Engineers often apply to both.
What is the salary of a DRDO Scientist B?
Pay Level 10 (₹56,100 starting basic) under the 7th CPC, with gross in-hand approximately ₹90,000–1,00,000/month in metro postings. Allowances include DA, HRA (24% X-class cities), Transport Allowance plus DRDO-specific Project Allowance (typically 25% of basic) on operational projects. Total CTC at entry level is approximately ₹13–15 lakh per annum.
Where are DRDO Scientist postings allocated?
DRDO has 50+ laboratories across India — Hyderabad (DRDL, ASL), Bengaluru (ADE, CABS, GTRE), Pune (ARDE, HEMRL, R&DE), Dehradun (DEAL, IRDE), Delhi (DIPAS, DRDE Gwalior nearby), Kanpur (CFEES) and many regional labs. Posting depends on lab vacancy, discipline match and the candidate's preference indicated during the application. Inter-lab transfer is possible after 3 years of service.
How can I prepare for the DRDO CoT written test?
The CoT engineering section mirrors GATE syllabus closely — so GATE preparation material works well. Focus on core engineering subjects (75% weightage) plus aptitude and general knowledge (25%). Use our syllabus hub for GATE-aligned topic weightage and previous papers for past CoT and GATE papers. Parallel PSU recruitments are tracked on the engineering jobs hub.
