The DRDO SSPL Walk-in Interview 2026 is exactly the kind of official, verified opportunity that’s worth putting on your radar if you’re a science or engineering postgraduate looking for a genuine research role — no online application, no lengthy portal registration, just a direct interview with your documents in hand. We picked this particular walk-in drive out of dozens of listings circulating online because it comes straight from DRDO’s own official vacancies page, backed by a dated, numbered advertisement rather than a recycled or unverifiable third-party post.
The Solid State Physics Laboratory (SSPL), a premier Delhi-based laboratory under the Defence Research and Development Organisation (DRDO), Ministry of Defence, has released Advertisement No. 625/SSPL/HR/JRF&RA/Rectt/2026-27/Main/01, inviting eligible candidates to a walk-in interview for 23 fellowship positions — Junior Research Fellow (JRF) and Research Associate (RA) roles in Physics and Electronics. If you’ve completed a postgraduate degree in these fields, or you’re a PhD holder or NET/GATE-qualified candidate, this guide walks you through everything you need to know before you show up at the venue.
Below, we cover eligibility, stipend, exact interview dates by discipline, the documents you’ll need, and the mistakes that trip up otherwise qualified candidates at walk-in interviews like this one — all sourced directly from the official DRDO notification.

What Is This Walk-in Interview About
Unlike most government recruitment drives that require weeks of online registration, document uploads, and admit card downloads, this is a direct walk-in interview — meaning eligible candidates simply show up at the specified venue on their designated date, with their documents and a completed application form in hand, and are interviewed on the spot.
The positions on offer are research fellowships, not permanent government jobs. Junior Research Fellows (JRF) and Research Associates (RA) work on DRDO research projects in Physics and Electronics, contributing to work in areas such as semiconductor materials, device fabrication, and characterization.
Why We Picked This Opportunity
Given how many “walk-in drive” listings circulate online — many of them recycled, outdated, or impossible to verify against an original source — we specifically looked for a drive that met a higher bar before recommending it:
- Directly sourced from DRDO’s official vacancies page (drdo.gov.in), not a third-party aggregator.
- Backed by a dated, numbered advertisement with a specific reference number, rather than a vague “walk-in job alert.”
- Currently open, with interview dates still upcoming at the time of publishing.
- A credible, well-known government organization — DRDO is India’s premier defence research agency, not an obscure or unverifiable employer.
If you’re browsing walk-in listings elsewhere, we’d encourage applying the same filter: always trace a walk-in notice back to the hiring organization’s own website before making travel plans to attend.
Organization Overview: SSPL and DRDO
The Solid State Physics Laboratory (SSPL) is a constituent laboratory of the Defence Research and Development Organisation (DRDO), functioning under India’s Ministry of Defence. SSPL is based in Timarpur, Delhi, and focuses on research in semiconductor materials, solid-state devices, and related electronics and physics domains that support India’s defence technology ecosystem.
DRDO itself is the umbrella organization responsible for the research and development of a wide range of defence technologies across the country, operating dozens of specialized laboratories like SSPL across different scientific disciplines.
Vacancy Details
| Position | Number of Fellowships |
|---|---|
| Junior Research Fellow (JRF) | 16 |
| Research Associate (RA) | 7 |
| Total | 23 |
Both disciplines covered are Physics and Electronics. As per the official advertisement, some of these vacancies are regular positions, while others are tied to specific DRDO projects — meaning a project-linked fellowship could conclude when that particular project is completed.
Eligibility Criteria
Junior Research Fellow (JRF)
You need one of the following combinations:
- A Postgraduate degree (M.Sc. or equivalent) in Physics or Electronics, with First Division, and a valid NET qualification
- OR a Graduate degree (B.E./B.Tech in Engineering Physics or Electronics) with First Division, and a valid NET or GATE score
- OR a Postgraduate degree (M.E./M.Tech) with First Division at both the graduate and postgraduate level
Upper age limit: 28 years (with relaxation for SC/ST/OBC candidates as per Government of India rules).
Research Associate (RA)
You need one of the following:
- A Ph.D. or equivalent degree in Physics or Electronics
- OR an M.E./M.Tech with at least 3 years of research experience specifically in Semiconductor Materials, Device Fabrication, and Characterization, along with at least one published research paper in a Science Citation Index (SCI) journal
Upper age limit: 35 years (with relaxation for SC/ST/OBC candidates as per Government of India rules).
Special note for PhD submission-stage candidates: If you’ve submitted your Ph.D. thesis but haven’t yet received your degree, you’re still eligible to apply for the RA position. However, the official advertisement clarifies that the Research Associateship will only be formally awarded once you’ve received your degree or provisional certificate, and that must happen on or before the date the fellowship offer is made.
Interview Schedule by Discipline
This is one of the most important details to get right — SSPL has scheduled separate interview dates for each specific role and discipline combination, so showing up on the wrong date means you won’t be interviewed.
| S. No. | Discipline & Position | Interview Date |
|---|---|---|
| 1 | JRF (Physics) | 1 September 2026 |
| 2 | RA (Physics) | 2 September 2026 |
| 3 | JRF (Electronics) | 8 September 2026 |
| 4 | RA (Electronics) | 9 September 2026 |
Double-check your exact date against your specific position and discipline before you travel — a Physics JRF candidate showing up on the Electronics date, for instance, would not be attending the correct session.
Venue and Reporting Time
- Venue: SJB Auditorium, SSPL Complex, Lucknow Road, Timarpur, Delhi-110054
- Reporting Time: 0930 hours (9:30 AM) on your designated interview date
- Contact: SSPL can be reached at 011-23903540 for official queries
Given that this is a Delhi-based, in-person walk-in with a fixed reporting time, plan to arrive well before 9:30 AM — government walk-in interviews often see long queues, and the official advertisement notes that a screening test may be conducted on the same date if the number of candidates turning up is high, which means your day could run considerably longer than a typical interview slot.
Stipend and Fellowship Terms
| Position | Monthly Stipend |
|---|---|
| Research Associate (RA) | ₹67,000 |
| Junior Research Fellow (JRF) | ₹37,000 |
A few important terms worth understanding before you apply:
- Selected candidates will be paid as per the provision of funds up to the Project Definition Completion (PDC) date of the relevant project — meaning project-tied fellowships are inherently linked to that project’s funding and timeline.
- The fellowship is purely temporary and does not confer any right to absorption or regular appointment within DRDO.
- The fellowship may be terminated at any time during the tenure with one month’s prior notice, and fellows may similarly resign with one month’s notice.
- No TA/DA (travel or dearness allowance) is admissible for attending the walk-in interview or for joining the position — you’ll need to cover your own travel costs to Delhi.
- No application fee is mentioned anywhere in the official notification.
Documents Required
Bring the following to your walk-in interview, as specified in the official advertisement:
- A duly filled application form (Appendix ‘A’, included in the official notification PDF)
- A recent passport-size photograph, affixed to the top-right corner of your Appendix ‘A’ form
- Attested copies of your mark sheets and degree certificates
- Caste certificate (if applicable, for reserved category candidates)
- Experience certificates (if applicable, particularly for RA applicants citing research experience)
- Copies of any published research papers (relevant for RA candidates, particularly those relying on their SCI publication)
- A No Objection Certificate (NOC) if you are currently working in a Government department, Public Sector Undertaking, or Autonomous Body
Important restriction: No electronic gadgets are allowed inside the SSPL lab premises, so plan accordingly and avoid carrying unnecessary devices on interview day.
Selection Process
Based directly on the official advertisement, the selection process works as follows:
- Document verification at the venue, where your application form and supporting certificates are checked against the eligibility criteria for your chosen position.
- Screening test (conditional) — if the number of candidates for a given discipline and date is large, SSPL may conduct a screening test on the same day before proceeding to interviews.
- Walk-in interview with the selection panel, assessing your technical background and suitability for the specific fellowship.
- Result and offer — selected and waitlisted candidates are typically informed following the interview process, based on standard practice for DRDO walk-in recruitments.
Since this is a fellowship position rather than a standard government post, there’s no separate written exam or multi-stage process beyond the interview (and possible same-day screening test) — everything happens in a single visit.
How to Attend the Walk-in Interview
- Confirm your eligibility against the specific qualification and age criteria for either JRF or RA, based on your discipline (Physics or Electronics).
- Download the official advertisement and Appendix ‘A’ application form from DRDO’s official website (drdo.gov.in) — do not rely on a third-party reproduction of the form.
- Fill out Appendix ‘A’ completely, including your personal details, qualifications, and experience, and affix a recent passport-size photograph in the top-right corner.
- Gather and attest copies of all required certificates, mark sheets, and (if applicable) your NOC and caste certificate.
- Plan your travel to Delhi in advance, keeping in mind that no TA/DA is provided.
- Arrive at SJB Auditorium, SSPL Complex, Timarpur, Delhi by 0930 hours on your correct discipline-specific interview date.
- Carry your original documents for verification alongside your attested copies — walk-in interviews typically require originals to confirm the authenticity of copies submitted.
There is no online application for this drive — you do not need to register on any portal in advance. Simply show up prepared, on the correct date, with your complete documentation.

Common Mistakes to Avoid
- Showing up on the wrong date for your discipline. With four separate dates split by position and subject, this is the single most common and entirely avoidable mistake for this specific drive.
- Forgetting to bring original documents. Attested copies alone are often insufficient without originals present for on-the-spot verification.
- Assuming TA/DA will be reimbursed. The official notification explicitly states no travel allowance is provided — budget your trip to Delhi accordingly.
- Applying for RA without meeting the SCI publication requirement, if relying on the M.E./M.Tech-plus-experience route rather than a Ph.D. Double-check this specific requirement carefully before assuming eligibility.
- Bringing electronic gadgets into the SSPL premises. This is explicitly prohibited and could cause avoidable delays or complications at entry.
- Not carrying a No Objection Certificate if you’re currently employed in a government role, PSU, or autonomous body — this is a mandatory document for such candidates.
- Trusting unofficial reproductions of the application form. Always download Appendix ‘A’ from the official DRDO notification rather than a third-party site, to ensure you’re using the correct, current version.
Expert Tips to Prepare
- Reconfirm your exact eligibility route before traveling. JRF and RA each have multiple qualifying paths (degree-plus-NET/GATE for JRF; PhD or experience-plus-publication for RA) — make sure you clearly qualify under at least one before committing to the trip.
- Prepare to discuss your specific technical background, especially around semiconductor materials, device fabrication, or characterization if you’re applying for the RA position, since these are explicitly called out as relevant experience areas.
- Organize your documents the night before, in the exact order listed in the advertisement, so you’re not scrambling at the venue.
- Arrive well ahead of 9:30 AM. Given the possibility of a same-day screening test for high candidate volumes, arriving early gives you a better position in the queue and more time before proceedings begin.
- Review your own research work or thesis carefully if you’re a Ph.D. or near-Ph.D. candidate, since the interview will likely explore your specific area of study in some depth.
- Keep a working phone number and email active, since result or offer communication typically follows up through the contact details you provide in Appendix ‘A’.
Who Should Seriously Consider This Opportunity
Not every candidate browsing walk-in listings is necessarily the right fit, and being honest about that upfront saves you a wasted trip to Delhi. The DRDO SSPL Walk-in Interview 2026 is worth pursuing seriously if:
- You hold a First Division postgraduate degree in Physics or Electronics and are NET-qualified, or a First Division B.E./B.Tech in Engineering Physics or Electronics with a valid NET/GATE score, and you’re under 28 — you’re a strong candidate for the JRF track.
- You hold a Ph.D. (or have submitted your thesis) in Physics or Electronics, or an M.E./M.Tech with three years of relevant research experience and at least one SCI-indexed publication, and you’re under 35 — the RA track is built for you.
- You’re specifically interested in semiconductor materials, device fabrication, or characterization research, since this is the stated technical focus of the SSPL fellowship roles.
- You’re based in or near Delhi, or can travel there at your own expense, since no TA/DA is provided for this walk-in.
On the other hand, if you’re looking for a permanent government appointment with long-term job security, it’s worth setting expectations correctly: this is explicitly a temporary research fellowship, not a regular DRDO appointment, and some of the 23 positions are tied to specific project timelines rather than being indefinite roles.
How This Walk-in Format Differs From a Standard Government Recruitment
If you’re used to typical Indian government recruitment — an online application, an admit card, a written exam, and eventually an interview — the DRDO SSPL Walk-in Interview 2026 will feel refreshingly different, and it helps to understand why before you show up unprepared for the format.
| Aspect | Standard Govt Recruitment | This DRDO SSPL Walk-in |
|---|---|---|
| Application Mode | Online registration, weeks in advance | No online application — bring documents directly |
| Written Exam | Often required | Not standard, though a screening test may occur on the same day if turnout is high |
| Admit Card | Issued after registration | Not applicable — no prior registration exists |
| Number of Stages | Multiple (prelims, mains, interview) | Typically a single-day process: verification, possible screening, interview |
| Timeline to Result | Weeks to months | Often faster, given the compressed single-visit format |
This compressed format is precisely why preparation matters more, not less, for a walk-in interview — you don’t get the buffer of multiple stages spread across months to correct a mistake. Everything happens in one visit, on one date, so arriving with complete, correctly organized documentation is non-negotiable.
