The Indian Oil Corporation Limited (IOCL) interview process for engineering graduates primarily hinges on your GATE score, which carries about 85% of the weightage.
If shortlisted, the selection involves four main steps:
Document Verification: Checking original credentials and NOCs.
Group Discussion (GD) & Group Task (GT): Assessing communication and teamwork through current affairs discussions and team problem-solving exercises.
Personal Interview (PI): A panel evaluates your core technical engineering knowledge, behavioral traits, and industry awareness.
Medical Examination: A final, stringent health check before the official employment offer is made.
