ESE

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.
