ISRO recruits engineers and scientists to design, build, test and operate satellites, launch vehicles, ground systems, payloads and scientific instruments. Major technical recruitments include Scientist/Engineer (SC) posts in disciplines such as Electronics, Computer Science, Mechanical, Electrical, and Civil; as well as technician and administrative posts. Selection is typically via a written/online test (CBT) focusing on domain technical knowledge and general ability, followed by interview / document verification for shortlisted candidates. ISRO roles emphasise engineering fundamentals, system-level thinking, reliability, and hands-on problem solving.
Typical exam information (what to expect)
-
Format: Computer Based Test (objective MCQs) for initial screening; some posts may include descriptive/subjective questions or separate papers.
-
Sections: Discipline-specific technical paper (majority of marks) + General Ability / Aptitude / English / General Knowledge component.
-
Duration & marking: Varies by notification (commonly 2–3 hours); negative marking is often applied for wrong answers.
-
Shortlisting: Based on CBT score → Interview (for some posts) / Document verification → Medical.
-
Eligibility: Engineering degree (B.E./B.Tech) or equivalent in the relevant discipline; age limits and experience requirements depend on the post.
