What Candidates Should Do Now
With 470 vacancies and applications closing on September 3, eligible candidates have a relatively short application window. Engineering aspirants should first confirm their exact discipline eligibility, while applicants for Marketing, Law and Quality Control positions should carefully verify their postgraduate qualification and experience requirements.
Candidates planning to appear for the September 24 CBT should also begin preparing simultaneously for the aptitude and domain sections. Since the Domain Knowledge section accounts for 50 of the 100 questions and the examination carries negative marking, focused subject preparation will be important. The notified September 15 admit card date and September 24 CBT date remain tentative and should be checked against any subsequent IOCL notice.
