• Drone warfare and autonomous navigation

• Cyber defence

This evolution affects the job profiles, eligibility requirements, and exam pattern candidates will likely encounter.

The Aspirant’s Story (Expert-Style Narrative)

Meet Aarav, a B.Tech graduate in Electronics. He once believed DRDO was only for top-ranked, 9-pointer engineers. But as he explored the CEPTAM recruitment workflow, he realized that success lies in structured preparation, pattern understanding, and strategic exam planning, not just academic brilliance.

This blog follows the same approach: helping you think like a real DRDO aspirant.

The Core Structure of DRDO Recruitment (Expected for 2025)

To help you analyze the recruitment process deeply, here’s the breakdown:

1. Tier-I (CBT)

Objective type, elimination stage.

2. Tier-II (Technical/Skill/Trade Test)

Hands-on or descriptive depending on the post.

3. Document Verification

4. Medical Examination

Conducted under strict standards.

This process has been steady over the years, but what’s changing in 2025 is the nature of competition, not the stages.

Detailed Insights Into Eligibility & Post Categories

1. Senior Technical Assistant (STA)

• B.Sc. / Diploma in Engineering

• Moderate difficulty, but technical depth matters

2. Technician (Tech-A)

• ITI qualification

• Practical knowledge essential

3. Admin & Allied Posts

• 10th / 12th / Graduate

• Includes Steno, Clerk, Store Assistant, Security Assistant

4. Scientist Posts

• Higher-level recruitment through RAC

DRDO exams require quick thinking, not just subject knowledge.

3. No mock test discipline

4. Copy-paste preparation strategies from others

5. Not reading the notification carefully

Tiny errors lead to disqualification.

6. Underestimating General Awareness

DRDO often includes science-related GK.
