Engineering Entrance Exam

The list of PSUs for ECE recruitment through GATE is listed below:
1- Airports Authority of India (AAI)
2- Bhabha Atomic Research Centers (BARC)
3- Indian Space Research organisation (ISRO)
4- NLC India Limited (NLC)
5- Hindustan Petroleum Corporation Limited (HPCL)
6- Nuclear Power Corporation of India Limited (NPCIL)
7- National Thermal Power Corporation (NTPC)
8- Electronics Corporation of India Limited (ECIL)
9- Power Grid Corporation of India Limited (PGCIL)
10- Oil and Natural Gas Corporation Limited (ONGC)
This can't be answered in the exact figure as it depends on the number of vacancies available in the Public Sector Undertakings. But if roughly estimated, including all Maharatna and Miniratna PSUs, It would be around 150 to 250, which varies per year.

GATE is also a qualifying test for many PSUs for ECE engineers. However, the following public sector units are recruiting through the GATE as well as sometimes they conduct their own exams. AAI- Airport Authority of India. BARC-Bhabha Atomic Research Centre. BBNL- Bharat Broadband Limited. BEL Bharat Electronics limited. BEML- Bharat Earth Movers Limited. BHEL- Bharat Heavy Electrical Limited. BSNL JTO- Bharat Sanchar Nigam Limited; Junior Telecom Officer. CEL - Central Electronic Limited
DMRC- Delhi Metro Rail Corporation. DRDO- Defence Research and Development organisation. ECIL- Electronics Corporation of India ltd. HAL- Hindustan Aeronautics limited. IOCL- Indian Oil Corporation of India. ISRO- Indian Space Research organisation. MDL-Mazagon Dock Shipbuilders Limited. NTPC - National Thermal Power Plant. NHPC- National Hydroelectric Power Plant. NLC- Neyveli Lignite Corporation Limited. OMPL- ONGC Bangalore Petrochemicals Limited. I hope this will help you.

The A.M.E. CEE Examination is a national level entrance exam that allows students who envision a career and have an interest in the aviation sector to choose the best career option for them. A.M.E. CEE will only organize and administer the online exam and will provide up to 100% scholarship based on their All-India Rank (AIR) for A.M.E. CEE 2023. Candidates who qualify for the A.M.E. CEE 2023 examination and wish to work in the aviation industry are eligible for admission to one of India's best A.M.E. Aeronautical Engineering, and Aerospace Engineering colleges or institutes with up to 100% scholarship. The A.M.E. CEE 2023 examination will be conducted once a year in an online and offline mode for the 12th PCM and 3 years engineering Diploma candidates.

The GATE is a national-level exam which is conducted in India that primarily tests the comprehensive understanding of various UG subjects in engineering and Science for admission into the M.E. /M.Tech. Ph.D. programme and Job in PSUs. However, the GATE exam is not conducted for JRF. The NTA has been entrusted by the UGC with the task of conducting UGC NET which is a test to determine the eligibility of Indian nationals for Assistant Professor and JRF and Assistant Professors in Indian colleges and universities. NET is a national-level test of the UGC for the award of a JRF to eligible students. PG students, who want to undertake research studies in the field of Engineering, Science, Humanities, Social-Sciences, or more can apply. I hope this will help you.

Electronics and Communication Engineering, Mining, Physics and Electrical are the toughest branches for the Graduate Aptitude Test in Engineering because of their competition. Lacs of students appear in the examination every year and due to this, the level of difficulty of the examination has risen day by day. The difficulty level of the GATE exam:
Electronics and Communication Engineering: Moderate to Difficult
