Selection Weightage: CBT vs Interview

For executive cadre appointments (Management Trainees and Officers), final selection is based on combined scores:

• CBT Score: 80% Weightage in overall merit calculation.
• Personal Interview: 20% Weightage in overall merit calculation.
• Trade Test (Operator/Technician): Purely qualifying in nature; final rank is determined strictly on CBT score.
