Check your exact degree and subject combination against the official table. A generally related engineering degree is not automatically equivalent to a listed combination. The undergraduate and postgraduate requirements are cumulative, not alternatives.
Marks, age and educational conditions
The undergraduate threshold is an aggregate minimum of 65% across semesters or CGPA 6.84 on a ten-point scale. The postgraduate threshold is at least 60% or CGPA/CPI 6.5 on a ten-point scale. Qualifications must have been obtained by 13 October and completed within the stipulated course duration. The notice contains a separate Section B rule for AMIE/Grade IETE candidates.
Rounding marks is not allowed. Where only CGPA is printed, it must itself meet the eligibility standard; converting it into percentage is not permitted for eligibility, even if an institution provides a formula. Separate rules apply to integrated or dual degrees. Professional courses pursued through open and distance learning are excluded. Foreign-degree holders must produce an AIU equivalency certificate at interview.
The age ceiling is 30 on 13 October. Ex-servicemen, persons with benchmark disabilities and departmental candidates may claim applicable Government of India relaxations. Applicants should read the notified physical requirements and their own eligibility conditions rather than assume that an unreserved vacancy has every category-specific concession.
Work described in the notice
Welding involves research and development concerning aerospace materials, including high-nickel high-strength alloys, stainless steels and non-ferrous materials. Turbo Machinery covers design, CFD studies, testing and performance analysis of launch-vehicle turbo machines. Power Electronics includes converter design, analysis and realisation, nano-satellite power systems and drive electronics for high-power BLDC motors.
Written test and interview
The selection process consists of a written test and personal interview. Part A is discipline-specific: 60 multiple-choice questions, 60 marks and 75 minutes, with +1 and minus one-third marking. Part B is an aptitude/ability test of up to 15 questions for 20 marks in 30 minutes, without negative marking. Part C contains discipline-related descriptive questions for 20 marks in 30 minutes.
The notice requires 50% in each written section, 50/100 in interview and 60% aggregate minimum under its qualifying table. Interview shortlisting is in a 1:5 ratio with a minimum of ten candidates. The final panel assigns 50% weight to the written test and 50% to interview. There is no travel allowance for the written test; interview rail-fare reimbursement is subject to the notice's conditions.
Fees and application steps
All applicants initially pay Rs 750. Fee-exempt categories—female, SC, ST, PwBD and ex-servicemen candidates—receive a full refund only if they attend the written test.
