Selection Process & Exam Pattern
IOCL’s selection consists of a Computer-Based Test (CBT) followed by a Skill/Proficiency/Physical Test (SPPT) (qualifying nature). The CBT is an objective MCQ exam of 100 marks/100 questions, duration 120 minutes. It covers three sections: Subject Knowledge (75 marks), Numerical Ability (15 marks), and General Awareness (10 marks). The test is bilingual (English & Hindi) and has no negative marking.
Candidates must secure at least 40% marks in CBT to qualify (35% for SC/ST/PwBD). Shortlisted candidates will then undergo SPPT – which assesses hands-on skills or physical fitness as required by the post (this is only qualifying). Final selection is based on the CBT score and SPPT qualification, with reservation and relaxed norms as applicable.
