Oil and Natural Gas Corporation Limited is an Indian multinational oil and gas company headquartered centered in Dehradun, India.

Exam pattern:
Test is objective as well as subjective (descriptive):
1) General Awareness (50 Marks):
a. 50 Objective Questions
b. 2 Descriptive Type Questions (5 Marks Each)
2) Subject Specialization (100 Marks)
a. 75 Objective Questions
b. 2 Descriptive Type Questions (5 Marks Each)
The specialization section has questions from the discipline in which the applicants has completed the degree for eligibility e.g. Electrical, Mechanical,Computer Science etc.
