Important Dates

Applications must be sent by Ordinary Post to Post Bag No. 001, Lodhi Road Head Post Office, New Delhi-110003. Dispatch at least 7–10 days before 12 July 2026 to account for postal transit time from non-metro cities – the last date is for receipt, not dispatch, and applications received after 12 July 2026 will not be considered regardless of postmark date.

Vacancy and Category Analysis

CS and EC candidates hold the strongest opportunity with 10 seats each – together accounting for 80% of all vacancies. With 25 total vacancies and candidates shortlisted at five times the vacancy count (125 candidates called for interview based on GATE score merit), the interview stage involves roughly 5 candidates competing per seat. CS and EC historically attract the largest GATE candidate pools; expected competition level is HIGH for these two subjects based on similar Cabinet Secretariat and DRDO technical recruitments in 2024–25, where CS and EC shortlist cutoffs typically exceed GATE scores of 650–700. Mathematics and Civil Engineering, with just 1 vacancy each, offer very low shortlist volume but also extremely concentrated competition – a single borderline candidate can shift the entire merit list. DA (Data Science/AI) with 3 seats is the emerging opportunity for candidates with specialisation in AI/ML at a time when such GATE paper participation is still relatively lower than CS.

Salary and In-Hand Calculation

The notification confirms total initial monthly emoluments of approximately ₹1,30,000 including all allowances for New Delhi posting. The breakdown at Pay Level-10 (entry cell) is as follows: Basic Pay ₹56,100; DA at current central government rate of approximately 55% (~₹30,855); HRA at X-class city rate of 27% of basic (~₹15,147) applicable to New Delhi posting; TA and other allowances approximately ₹5,000–₹8,000. This gives a gross of approximately ₹1,07,000–₹1,10,000 plus NPS employee contribution at 10% of basic (~₹5,610). The ₹1,30,000 figure cited in the notification represents total emoluments inclusive of all allowances before deductions.

Compared to DRDO Scientist-B posts at the same Pay Level-10 which offer approximately ₹95,000–₹1,05,000 total emoluments in non-metro postings, this Cabinet Secretariat post offers higher take-home specifically due to the New Delhi X-class HRA of 27% versus the 9% HRA applicable at most DRDO lab locations – a difference of approximately ₹10,000–₹12,000 per month in HRA alone.

Candidates posted in New Delhi receive X-class HRA at 27% of basic (₹15,147 per month), which is ₹10,098 more per month than a Y-class city HRA posting at 18% – a difference of approximately ₹1,21,176 annually purely in HRA benefit.

Application Fee

No application fee is mentioned in the official advertisement. Candidates are advised to verify from the official notification before applying, as Cabinet Secretariat recruitments have historically not charged any examination fee for Group-A technical posts.

Age Limit

Age is calculated as on the closing date of 12 July 2026. A General category candidate born on 12 July 1991 turns exactly 35 on the closing date and is eligible on the boundary. A candidate born on 13 July 1991 is not eligible under General category. Central Government employees seeking age relaxation must submit an Annexure-IV certificate from the Competent Authority of their current employer along with the application.

Eligibility Criteria

The most common eligibility mistake for this post type: candidates confuse GATE percentile with GATE score. A GATE score of 500 out of 1000 (50%) is the requirement – this is not the same as 50th percentile. A score of 500 can correspond to significantly higher than the 50th percentile in competitive papers like CS and EC. GATE 2023 and earlier scores are not valid – only GATE 2024 or GATE 2025 score cards are accepted. MSc in the corresponding science subject is explicitly eligible alongside BE/BTech; candidates should confirm their MSc subject maps to the corresponding GATE paper code.

Selection Process

Stage 1: GATE Score Shortlisting

All applications are ranked by valid GATE Score for each subject separately. Candidates shortlisted at five times the number of vacancies per subject are called for interview – meaning 50 candidates for CS (10 seats), 50 for EC (10 seats), 15 for DA (3 seats), 5 for Mathematics (1 seat), and 5 for Civil Engineering (1 seat). Only GATE scores from 2024 or 2025 with a minimum of 500 (50%) qualify for shortlisting. Begin preparing for the interview as soon as you apply – the gap between application and interview call can be as short as 4–6 weeks for central government technical drives.

Stage 2: Interview (Character and Antecedent Verification + Medical Examination)

The interview carries 20 marks out of the total 120 (GATE 100 + Interview 20). It is merit-based and contributes to the final selection rank alongside the GATE score. Character and antecedent verification and a medical examination are conducted before final appointment. Prepare to discuss your GATE subject area in depth – Cabinet Secretariat technical interviews are known for assessing applied knowledge relevant to intelligence and field operations contexts. Exact date, time, and centre of interview will be communicated only by email to shortlisted candidates.

Your first 7 days after applying:

1. Send your application by Ordinary Post immediately – do not use Speed Post or Courier; the notification specifies Ordinary Post to Post Bag No. 001, Lodhi Road Head Post Office, New Delhi-110003
2. Keep a self-attested copy of your GATE 2024 or 2025 Score Card ready – it must be enclosed with the hard copy application
