The online application must be completed by April 10, 2024, and applications must be submitted by April 30, 2024, to be considered for the positions. The time frame for corrections is May 27, 2024–May 20, 2024. The UPSC IES ISS Application Form 2024 is available to candidates at both upsconline.nic.in and upsc.gov.in. Class 1 officers, or engineers employed by the Indian government, make up the Indian Engineering Services (IES), sometimes called the Engineering Services Examination (ESE). They are selected to serve the Indian government in managerial and technical capacities. A total of 1056 positions are expected to be open for UPSC CSE in 2024, 40 of which are designated for candidates with baseline disability categories.

The Union Public Service Commission (UPSC) releases the admit cards for the IES Preliminary Exam a few weeks before the exam date.The IES 2024 admit card was released online on February 9, 2024.he IES 2024 admit card was released online on February 9, 2024. The Commission conducted the IES Prelims 2024 exam on February 18, 2024. The candidates were required to carry the same photo identity proof whose number was entered in the IES 2024 applications.The process of downloading the admit card generally involves visiting the UPSC website, logging in with the candidate's registration credentials, and accessing the admit card download link. Once available, candidates can download and print their admit cards, which contain essential details such as exam date, time, venue, and instructions for the examination.
