What's Official: Your Gateway to India's Space Program
The Indian Space Research Organisation (ISRO) has opened online applications for 93 Scientist/Engineer 'SC' positions, offering a coveted Group 'A' Gazetted career to engineering graduates. This recruitment drive, overseen by the ISRO Centralised Recruitment Board (ICRB) under Advertisement No. ISRO:ICRB:02(EMC-CEPO):2026, is a golden opportunity across seven engineering disciplines.
Crucially, this cycle stands out for its unique selection process: no written examination. Candidates are shortlisted directly based on their GATE 2025 or GATE 2026 scores, followed by an interview. The application window commenced on July 28, 2026, and will close sharply on August 17, 2026, with fee payment accepted until August 19, 2026. This notification has generated significant buzz among aspirants due to its streamlined selection directly from GATE to interview.
Tip
Ensure your GATE score for 2025 or 2026 is valid and directly matches your applied engineering discipline.
Vacancy Details & Your Strategic Shot
A total of 93 vacancies are available across various engineering streams. This includes 92 Group 'A' Gazetted posts within ISRO/Department of Space centres and one Non-Gazetted Civil post at the Physical Research Laboratory (PRL), an autonomous body. Understanding this discipline-wise breakdown is key to assessing your competitive landscape.
Tip
The concentration of vacancies in Electronics, Mechanical, and Computer Science means intense competition. Civil, Electrical, Refrigeration & Air Conditioning, and Architecture, though fewer posts, offer a distinct challenge.
Eligibility at a Glance: Do You Qualify?
Meeting the stringent eligibility criteria is non-negotiable for an ISRO Scientist/Engineer 'SC' post. Here's what you need to know:
Your educational qualification must be a BE/B.Tech (or a Bachelor's degree in Architecture for the Architecture post) in the relevant discipline. A minimum of 65% aggregate marks (averaged across all semesters) or an equivalent CGPA of 6.84 on a 10-point scale is mandatory. Ensure your degree is from a recognised institution.
A valid GATE 2025 or GATE 2026 score is paramount. The paper code of your GATE score must precisely match the discipline you are applying for. ISRO conducts independent verification of GATE scores; any discrepancy will lead to immediate disqualification. Old GATE scores or scores from allied branches will not be accepted. The maximum age limit for General/EWS candidates is 28 years as of August 17, 2026. Age relaxations apply for reserved categories as per Government of India norms.
Tip
Double-check your GATE paper code against the required discipline to avoid disqualification. No room for error here.
The ISRO Selection Process: No Written Test Here
Unlike many other central government science postings, the ISRO Scientist/Engineer 'SC' recruitment stands out by entirely bypassing a written examination. Your journey to ISRO is a two-stage process:
The initial shortlisting is based purely on your GATE score (not GATE marks or All-India Rank). ICRB shortlists candidates for the interview in a strict 1:7 ratio. This means for every single vacancy, only seven candidates will proceed to the interview stage. A strong GATE score is your ticket to this crucial stage.
The Interview carries 100 marks and is designed to thoroughly assess candidates across multiple dimensions. Expect questions evaluating your technical and academic knowledge, subject-specific general awareness, presentation and communication skills, comprehension, and your overall academic achievements, including institute pedigree and CGPA/percentage. For Electronics, Mechanical, and Computer Science, the final merit list is determined by assigning a 50% weightage to your GATE score and a 50% weightage to your interview performance. Unreserved candidates must secure a minimum aggregate of 60% (with relaxations for reserved categories). A similar weightage system applies to all other disciplines. Candidates who successfully clear the interview will then undergo comprehensive document verification and a medical examination.
Tip
Your GATE score opens the door, but your interview performance seals the deal. Prepare for a rigorous technical assessment.
Strategic Interview Preparation & Expected Cutoffs
Given the direct-to-interview model, your preparation strategy must pivot heavily towards deep technical understanding and effective communication. Revisit core engineering concepts relevant to your discipline, focusing on fundamental principles, applications, and recent advancements in space technology if applicable. Be ready to articulate complex ideas clearly and concisely. Practicing interview simulations and technical discussions is crucial.
While official cutoffs are released post-selection, historical trends suggest that to be shortlisted for the interview in a 1:7 ratio, a very high GATE score is imperative, especially for disciplines with more vacancies like Electronics, Mechanical, and Computer Science. Expect the GATE score cutoffs for interview shortlisting to be competitive, often in the top percentiles. The final merit list also gives substantial weight (50%) to your GATE score, reinforcing its importance throughout the process. Candidates should aim for an excellent performance in both their GATE exam (for shortlisting) and the interview (for final selection). For refining your conceptual clarity and problem-solving approach to tackle challenging technical interview questions, diligent practice on platforms like Aspirant Arcade can provide the edge you need.
Tip
Focus on both depth and breadth in your core engineering subjects. Your ability to explain concepts and solve problems on the spot will be key.
