ESE

The application fee for IES 2024 prelims is INR 200. UPSC conducts the IES exam every year to recruit candidates for various specialised positions in the Union Government departments. The IES is a Central Civil Service and the candidates can be posted anywhere across the nation. The exam is conducted to recruit candidates for engineering positions for the various departments working under the Government of India. soon. The UPSC IES 2024 main exam was conducted on June 23, 2024. UPSC ESE 2024 (IES) main result was released on July 31, 2024. The Commission released the roll number and the names of the candidates who will be eligible for the UPSC ESE (IES) 2024 interview stage. 

In the formal notification, the Union Public Service Commission listed 167 vacancies. The Commission withheld the information regarding the service-wise openings for the IES 2024 exam. Candidates should anticipate the greatest number of openings in the mechanical or civil engineering categories, based on trends from the previous year. The official IES 2024 notice included information about available positions. The low amount of IES 2024 vacancies should cause candidates to expect a higher IES cutoff. IES openings significantly impact the cutoff. The date of the IES 2024 exam was February 18, 2024. September 26, 2023, was the deadline for applications to the IES 2024 exam.
