How to Get Internship in ISRO: Application Process

To get into ISRO as an intern or project trainee, you must follow the general/ standard process. Below is a step-by-step breakdown, including centre practices, document tips, and submission routes.

Step 1: Choose the Right Scheme & Centre

• ISRO offers two main schemes: the Internship Scheme (for short durations, up to ~45 days) and the Student Project Trainee Scheme (longer durations, aligned with academic projects).
• Each centre/ unit (e.g., URSC, SAC, VSSC, IIRS, ISAC, etc.) handles its own internship/ project work announcements.
• Choose a centre whose research domain matches your specialization (e.g., remote sensing, electronics, propulsion, astrophysics) and focus on the internship requirements of these centres to increase your chances of getting an internship in ISRO.
• For this, review the ISRO “Internships & Projects” page for links to each centre’s internship pages.

Step 2: Collect & Prepare Required Documents

Before applying, ensure all your documents are ready and formatted correctly. Here is what you will generally need when applying for an internship in ISRO:

• Updated Resume/ CV: Your resume must highlight relevant coursework, projects, tools, and skills.
• Academic transcripts/ mark sheets of prior semesters. Make sure you meet the eligibility requirements.
• Many centres require a bona fide certificate/ NOC/ college recommendation letter (on letterhead, signed by HOD / Principal), so have them ready on hand.
• Request/ cover letter/ application letter addressed to the centre/ lab, stating your project interest, duration, and alignment with the centre’s work.
• Photo ID (Aadhaar, Passport, etc.).
• Passport-size photographs (if required by that centre).
• Any project proposals, prior publications, or technical work to strengthen your case.

Step 3: Submit Application to the Centre / Unit

• Many centres use online application portals for internships. Check the centre’s internship/ student project page.
• Ensure you adhere to submission guidelines: document formats, labeling, order, file types, and signatures.

Step 4: Selection/ Scrutiny by the Centre

• The centre screens applications based on domain fit, academic performance, project alignment, and engineering/ science specializations. So make sure you align with them.
• Centres also select candidates based on available expertise, project, and facility availability.
• Notifications of acceptance or rejection are typically sent by email.

Step 5: Offer, Onboarding & Execution

• Once selected, you’ll receive an offer letter stating project duration, reporting centre, supervisor, and other formal conditions.
• Upon joining, you’ll be inducted, given a project brief, access to facilities, and guidelines about submission & evaluation.
• Interns/ project trainees must complete and submit a project/ assignment report, which is evaluated by the centre. Certificates are issued upon satisfactory performance.
• Note that interns/ project trainees aren’t generally eligible for any stipend, financial assistance, or accommodation under the standard ISRO scheme. Though there may also be instances of paid internships, they greatly vary.

Tips to Improve Your Chances of Getting an ISRO Internship

1. Tailor Your Application to Centre & Domain: Research the specific ISRO centre’s projects (e.g., SAC, VSSC, URSC) and align your skills and interests. Don’t send a generic SOP; mention the lab, domain, and how your background fits.
2. Highlight Relevant Projects / Research Experience: Prior work in space systems, electronics, remote sensing, simulation, or academic project work gives you credibility. Craft your resume to showcase this in the best way possible, and make a lasting impression.
3. Meet or Exceed Academic Benchmarks: ISRO requires a minimum of 60% or a CGPA of  6.32 (on 10) across courses. While this is the minimum benchmark, exceeding this shows consistency and seriousness, increasing your chances of getting an internship in ISRO.
4. Get Good Recommendations/ Institutional Backing: A recommendation from professors or having departmental support/ NOC shows legitimacy and trust. Sending a recommendation even when not required might earn you extra brownie points.
5. Get Relevant Certifications or Skills: Learn domain-specific tools (e.g., MATLAB, Python, simulations, remote sensing software) and/or get certifications in those.
6. Apply Early & Watch Centre Websites Closely: Many ISRO centres publish internship calls at different times (e.g., SAC’s “Vyom / SRDT” portal). Being first and prompt helps increase your chances, so keep an eye out for openings periodically.
7. Prepare for Interviews & Technical Questions: Be ready to defend your project work, domain knowledge, and motivation.
8. Follow Instructions & Format Rigorously: Use correct document formats, naming, and signatures, and follow lab-specific instructions. Missing small format rules is often a rejection reason.
9. Express Genuine Passion & Motivation for Space Work: ISRO values commitment. In your SOP and interviews, show that you care about space missions and R&D, and are not just chasing prestige.
