DRDO's Combat Aircraft Systems Development and Integration Centre (CASDIC), Bengaluru, has invited applications for a six-month paid internship for eligible final-year B.E./B.Tech students and second-year M.Sc. students. Advertisement CASDIC/HRG/PDINTERN/2026/01 lists 30 places across electrical and electronics-related disciplines, computer science and information technology, and mechanical engineering. The advertised stipend rate is ₹5,000 per month, subject to the notice's attendance and completion conditions. This is an onsite student internship, not a permanent recruitment drive or a work-from-home opportunity.
Important deadline clarification: DRDO's official vacancy webpage, the English application instructions and the advertisement's main dates table state 11 October 2026. However, one Hindi sentence in section 3(e) states 18 September 2026. This article uses the date supported by the webpage and main table while explicitly flagging the inconsistency. Applicants should confirm the deadline with CASDIC and avoid waiting until the final day. We have not received an independent clarification from the centre.

Disciplines and available places
The advertisement divides the 30 places into three branch codes. The code matters because applicants must identify their branch in the application and email subject. Use the discipline wording in the official notice rather than assuming that every related degree is automatically accepted.
- EC — 12 places: Electrical; Electronics and Communication; Electronics and Telecommunication.
- CS — 13 places: Computer Science and Information Technology.
- ME — 5 places: Mechanical Engineering.
Although the notice invites M.Sc. students, it does not provide a separate detailed list mapping every M.Sc. specialisation to these branch codes. Students whose qualification does not clearly match a listed discipline should ask CASDIC before claiming eligibility. The organisation also reserves the right to change vacancy positions or selection criteria during the process.
Who can apply?
Engineering applicants must be studying in the final year of their B.E. or B.Tech programme. M.Sc. applicants must be in the second year of their postgraduate programme. The course must be full-time and in the relevant discipline at an AICTE- or UGC-approved college or university. The application form specifies Indian nationality.
For engineering students, the stated academic requirement is a minimum CGPA of 7.5 in all previous semesters. For postgraduate science students, the notice requires at least 70% in the first-year examination. Applicants must also provide the formula used for CGPA conversion. Do not substitute an unofficial conversion calculation for the formula applicable to your institution.
The age requirement is below 25 years. The notice does not clearly specify a separate age-calculation date or a relaxation table, so neither is assumed here. Students close to the limit should obtain clarification from CASDIC. Meeting the academic threshold does not guarantee selection: the process remains merit-based and the number of places is limited.
Stipend, attendance and living costs
The ₹5,000 figure is the monthly stipend rate, not a promise that money will arrive every month. The first instalment is payable after three months of internship, and the second after completion of six months. Payment goes directly to the student's bank account.
The stipend applies only when the intern attends the laboratory for at least 15 working days in a month. This condition requires physical participation at CASDIC; it must not be presented as permission for remote work or as a complete weekly work schedule. Students should discuss academic release and attendance arrangements with their college before applying.
Boarding and lodging costs are the candidate's responsibility, with no reimbursement provided under the notice. Anyone relocating to Bengaluru should therefore plan accommodation and living expenses separately, including the period before the first instalment. The advertisement also states that leaving the internship midway means no completion certificate and no payment.
Programme scope and selection
CASDIC describes its work as electronic warfare systems for the Indian Air Force. That provides the organisational setting for the internship, but the advertisement does not assign a public project title, software stack or day-to-day task list to each discipline. Specific project responsibilities should be confirmed through the centre's selection and joining process.
Selection is based on marks in previous examinations and an online interview or interaction where required. Only selected students will receive joining instructions through the email address supplied in their application. Incomplete, incorrect or late applications may be rejected, and the notice says further correspondence about rejected applications will not be entertained.
The programme is educational training. CASDIC and DRDO do not undertake to offer employment after it ends, and completion does not create a right to a job. A certificate requires successful completion of the full internship, project evaluation, submission of the project report and other applicable formalities.
How to apply
- Open the official DRDO vacancy page. Use the link below and download the advertisement with its prescribed application and college-letter formats.
- Check your branch and eligibility. Review the year of study, academic threshold, full-time enrolment and age condition before assembling documents.
- Complete the prescribed form. Enter your personal and college details, discipline, branch code, degree, academic results, achievements and contact information accurately.
- Obtain your college's reference or request letter. It must use college letterhead and follow the attached format, with the appropriate institutional signature.
- Prepare readable scans. Include the completed application and the required supporting documents listed in the next section.
- Email the application to hrd.casdic@gov.in. The subject must identify the 2026 paid internship application and your branch code, following the wording in section 3(c) of the notice.
- Keep a copy of the submission. Check the recipient, attachments and branch code before sending, and retain the sent email for your own records.
Applications are accepted by email only; a posted hard copy is not an accepted application route. No closing hour is specified. Given the conflicting Hindi date, applicants should confirm the timeline rather than assume a midnight deadline. The notice also says that candidates who applied against the August 2025 paid internship advertisement need not apply again; those applicants should seek clarification about their existing application instead of automatically resubmitting.
Documents needed with the application
- The completed application in the attached official format.
- Self-attested copies of marksheets for all previous semesters.
- A self-attested Aadhaar copy.
- The college reference or request letter on institutional letterhead, using the prescribed format.
- A short biodata of fewer than 300 words highlighting achievements.
- The applicable CGPA-conversion formula, as required by the application instructions.
Use the official form's checklist as well as the advertisement's document list. These are application-stage documents; the more extensive joining requirements below apply to selected students. No application fee is specified in the advertisement, and this article does not add a payment step.
What selected students need at joining
Selected applicants must bring original previous-semester or year marksheets, their college reference letter and a bonafide certificate for verification. A college NOC on letterhead must confirm release for the internship and physical attendance for at least 15 working days each month. Original Aadhaar and college identity cards are also required.
The joining list additionally includes a police-verification certificate from the student's hometown or place of residence, bank details for stipend transfer and four passport-size colour photographs. Students must provide the supplied undertakings concerning the Official Secrets Act and the Ministry of Defence's applicable IT rules. Originals are to be returned after verification; further document requirements may be communicated by CASDIC.
Dates, clarification and official links
The main dates table lists application receipt by 11 October 2026, intimation to selected students on 13 November 2026, and the internship starting on 1 December 2026. These are the advertised dates, not a guarantee against later official changes. The conflicting 18 September Hindi line remains unresolved, so check for updates and contact the centre if necessary.
For clarification, the notice provides 080-25047686, available during working hours from 10 AM to 4 PM. The application email is hrd.casdic@gov.in. Confirm discipline equivalence, any age-related uncertainty and the date inconsistency directly with the organisation.
