UPSC Engineering Services Examination (ESE/IES)

UPSC Engineering Services Examination (ESE), often referred to as IES, is a competitive recruitment examination for engineering services and posts of the Central Government. The notified services are grouped by Civil, Mechanical, Electrical, and Electronics & Telecommunication engineering categories; the exact services and vacancies are set afresh in each annual notice.

The services listed in the 2025 notice illustrate the range of possible outcomes: Central Engineering Service, Border Roads Engineering Service, Indian Defence Service of Engineers, Central Water Engineering Service, Indian Naval Armament Service, Indian Telecommunication Service, and Indian Radio Regulatory Service, among others. Candidates are ultimately allotted based on merit, stated preferences, available vacancies, and medical fitness.

• Treat the annual UPSC notification—not coaching material or an older notice—as the authoritative source for the year’s participating services, vacancies, discipline mapping, reservations, and physical/medical requirements.
• A candidate applies in one engineering category for that examination cycle; choosing the appropriate discipline is therefore a central application decision.

Eligibility is cycle-specific. In the 2025 notice, the standard age band was 21 to 30 years as of January 1, 2025, with specified relaxations, including certain provisions for eligible Government servants and reserved categories. Applicants should calculate eligibility against the cut-off date and relaxation rules in the notice for their own cycle rather than relying on a previous year’s dates.

The standard educational route is an engineering degree from an eligible Indian university or institution. UPSC’s 2025 notice also listed certain professional and foreign qualifications, including Sections A and B of the Institution of Engineers (India) examinations, subject to the notice’s stated conditions. Some electronics-related posts permit designated M.Sc. qualifications. Final document verification and service-specific medical/physical fitness requirements remain material to appointment.

• Nationality conditions in the published notice include Indian citizens and specified other categories, some of whom require a Government of India eligibility certificate before appointment.
• Candidates who are awaiting the qualifying result may be allowed to apply provisionally under the notice’s rules, but must furnish proof of passing within UPSC’s prescribed window if called for the Personality Test.
• Read the current notice carefully if using AMIE or another professional qualification, because recognition and service-specific conditions can matter.

The published ESE scheme has three stages. Preliminary/Stage-I contains two objective multiple-choice papers worth 500 marks in total: General Studies and Engineering Aptitude (200 marks) and a discipline-specific paper (300 marks). Wrong answers in the objective papers attract a deduction of one-third of the marks assigned to the question; unanswered questions carry no negative mark.

Main/Stage-II consists of two conventional, discipline-specific papers of three hours each, worth 300 marks each (600 marks total). Stage-III is a 200-mark Personality Test. The published plan states that marks from all three stages determine final ranking; allocation also takes account of rank, service preferences, vacancies, and medical fitness. Conventional papers are to be answered in English.

• The relevant discipline-specific paper is Civil, Mechanical, Electrical, or Electronics & Telecommunication Engineering.
• UPSC sets qualifying standards and shortlists candidates from Preliminary to Main and from the written stages to the Personality Test; do not assume a fixed cut-off.
• The Personality Test assesses qualities including leadership, initiative, intellectual curiosity, practical application, and integrity.

UPSC requires online application through its application portal. In the cited notice, candidates first completed One Time Registration (OTR), then submitted the examination application and supporting information/documents for claims such as date of birth, category, and educational qualification. Admission is provisional until UPSC verifies eligibility against original documents at the appropriate stage.

Fees, exemptions, correction windows, photograph requirements, payment modes, and application closing times are cycle-dependent. As dated context only, the 2025 notice specified a ₹200 examination fee for candidates other than women and SC/ST/PwBD candidates, who were exempt subject to the stated rules. Applicants should use the current-year notification and portal instructions before paying or submitting.

• Register or sign in through UPSC’s online application portal, then select the ESE cycle when applications are open.
• Keep reliable proof for age, qualification, category and any claimed relaxation or fee exemption; the notice requires supporting information and later original-document verification.
• Download the e-admission certificate from UPSC when issued; UPSC does not send it by post under the cited notice.

Begin with the current notification’s examination plan and syllabus, then organise preparation around both components of Preliminary: General Studies and Engineering Aptitude, plus the chosen discipline paper. Because Main is conventional/descriptive and carries 600 marks, preparation should include structured written solutions and timed three-hour practice—not only objective-question practice.

Use UPSC’s own previous-year question-paper archive to inspect the actual paper types and recurring disciplinary coverage. The archive currently includes 2026 preliminary papers for General Studies and Engineering Aptitude plus each engineering discipline, as well as 2026 main papers across the four disciplines. Match timed practice to the official marks, durations, and negative-marking rules in the notification.

• Build separate practice routines for Preliminary MCQs and Main descriptive answers.
• Practise the 200-mark General Studies and Engineering Aptitude paper alongside the 300-mark discipline paper; neither should be treated as optional.
• For the Personality Test, prepare to explain engineering fundamentals, work or project experience, public-service motivation, and professional judgement; UPSC identifies leadership, initiative, practical application and integrity as assessment areas.

A successful candidate is recommended and allotted to a notified engineering service or post rather than receiving a generic engineering credential. Potential appointments depend on the discipline category, year-specific vacancy position, candidate rank, preferences, reservation rules, service eligibility, and medical fitness. The precise list can change from one ESE notice to another.

Examples from the cited 2025 notice include civil-side positions in Central Engineering Service, Border Roads Engineering Service and Central Water Engineering Service; defence and naval engineering roles across several disciplines; and electronics/telecom roles in Indian Telecommunication Service and Indian Radio Regulatory Service. This makes ESE a pathway into technical public-service careers, but not a guarantee of any particular named post.

• Final rank is based on Preliminary, Main and Personality Test marks under the published scheme.
• Service preferences matter, but allocation is constrained by rank, vacancies, applicable rules, and fitness requirements.
• Candidates finally recommended by UPSC are required to undergo medical examination under the cited notice.
