COMPANIES HIRING THROUGH GATE EXAM

BHEL, NTPC, Powergrid and Indian Oil have issued notifications for recruitment of Engineering Trainees through GATE Score

Graduate Aptitude Test in Engineering (GATE) is an all India examination administered and conducted jointly by the Indian Institute of Science and seven Indian Institutes of Technology on behalf of the National Coordination Board - GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India. The GATE is conducted for admission into Masters Degree in IITs and IISc. However, the scenario has changed now as major companies are using it as a platform to identify the suitable engineers/researchers in various areas. GATE 2012 score is the first step in these companies to filter the candidates in their selection process. They have made it mandatory for the students to have GATE score in the concerned subject for which the companies are seeking to recruit. Thus, the major companies do not only use GATE as an admission test but also as a means of recruitment option. As the new recruitment process has started from 2012, the importance for GATE has increased and more number of students are expected to take the GATE. As of now 4 companies have issued notification to recruit engineer trainees through GATE score. The number of companies to use this selection process would rise keeping in view of the importance of GATE.
