Expert Preparation Tips
IOCL primarily uses GATE scores — prepare comprehensively for GATE in your engineering discipline as a primary strategy
PI preparation: study IOCL's refinery operations, new greenfield projects, Cauvery Basin Refinery, and petrochemicals expansion plans
Technical questions for non-GATE cycles are at GATE level — cover all core subjects from standard textbooks
GK should cover petroleum sector news, India's energy security policy, and IOCL's recent annual revenue and rank achievements
