An instrumentation engineer interview typically involves technical questions on topics like process control, sensors, calibration, and programming (PLC, SCADA, DCS). Interviewers also assess practical experience through project discussions, evaluate troubleshooting skills, and gauge soft skills like communication and teamwork. The procedure includes rounds covering technical knowledge, hands-on experience, behavioral scenarios, and a final discussion.
