Preview Questions Process Engineer | Role Specific Skill

Question 1: Which of the following methods is used to ensure process safety during optimization in hazardous operations?

Which action should you take?

Choose only one option

Total Productive Maintenance (TPM)

HAZOP (Hazard and Operability Study)

Six Sigma

Kaizen methodology

Question 2: When optimizing a process, what is the primary focus of Six Sigma methodology?

Which action should you take?

Choose only one option

Increasing process speed without regard for quality

Cutting costs in the shortest amount of time possible

Focusing on customer satisfaction by reducing operational costs

Reducing defects and process variation by identifying and eliminating root causes

Question 3: How do you handle an intermittent fault in a control system that is difficult to reproduce during regular operation?

Which action should you take?

Choose only one option

Perform continuous monitoring, logging, and use diagnostic software to capture fault data when it occurs

Replace the entire system without understanding the fault

Increase the system's capacity and assume the issue will disappear

Ignore the fault until it occurs again and hope it is fixed automatically

Question 4: In troubleshooting a system with erratic temperature control, which component is most likely to fail?

Which action should you take?

Choose only one option

Heating element

Temperature sensor

Actuator valve

Pressure relief valve

Question 5: What is the key difference between centralized and decentralized control systems in a manufacturing process?

Which action should you take?

Choose only one option

Decentralized control requires less hardware than centralized control

Decentralized control uses a master controller for each process, while centralized control uses distributed controllers

Centralized control is limited to linear systems, while decentralized control can handle nonlinear systems

Centralized control uses a single controller for the entire system, while decentralized control uses individual controllers for each process unit

Question 6: What technique would you use to identify process shifts or abnormal variations in manufacturing data?

Which action should you take?

Choose only one option

Apply control charts (e.g., X-bar, R-chart) to detect shifts in process data and identify root causes

Use simple averages to detect variations

Assume all data points are normal without checking for shifts

Ignore small variations and focus only on large shifts
