Finolex Cables Process Engineer Interview: Rounds, Questions and Preparation

What the job involves

A Process Engineer in manufacturing, automobile, and engineering sectors (e.g., cable manufacturing like Finolex Cables) optimises production processes to improve yield, reduce cycle time, and ensure quality. Day to day, they monitor line parameters, troubleshoot defects, run trials, and coordinate with production and quality teams. They also document SOPs, analyse data, and drive continuous improvement projects.

Role and Technical Knowledge

1. 1

   Explain the extrusion process used in cable manufacturing. What are the key parameters you would monitor?

   Cover the basic steps: feeding, melting, die extrusion, cooling. Mention parameters like temperature profile, screw speed, line speed, and diameter control.

2. 2

   What is the difference between Cp and Cpk? How would you use them in a cable insulation process?

   Define Cp as potential capability and Cpk as actual capability considering centering. Explain how they indicate if insulation thickness is within tolerance.

3. 3

   What are the common defects in drawn copper wire and how can they be prevented?

   Mention defects like surface scratches, diameter variation, breaks. Prevention: proper lubrication, die maintenance, tension control, and speed optimisation.

4. 4

   Describe a typical process flow for manufacturing a PVC-insulated cable from raw material to finished product.

   Outline steps: compounding, wire drawing, annealing, extrusion, cooling, testing, and winding. Highlight quality checks at each stage.

Practical Scenarios

1. 5

   You notice a sudden increase in cable diameter variation on the extrusion line. How would you troubleshoot?

   Use a systematic approach: check material consistency, screw and die wear, temperature fluctuations, and puller speed. Suggest immediate corrective actions and long-term fixes.

2. 6

   A batch of cables fails the high-voltage spark test. What steps would you take to identify the cause and prevent recurrence?

   Investigate insulation defects, contamination, extrusion parameters, and raw material quality. Recommend rework or scrap, and implement SPC or supplier checks.

3. 7

   Your production line is consistently achieving lower output than target. How would you analyse and improve it?

   Calculate OEE, identify bottlenecks (e.g., changeover time, minor stops), and apply lean tools like SMED or 5S. Propose a pilot improvement and measure impact.

4. 8

   You are asked to reduce material waste by 10% in the compounding area. What data would you collect and what actions would you propose?

   Collect data on batch weights, scrap rates, and reject reasons. Suggest better weighing accuracy, operator training, and reuse of clean scrap where permissible.

Behavioural and Teamwork

1. 9

   Describe a time when you worked in a team to solve a technical problem during your project or internship.

   Use STAR format: situation, task, action, result. Emphasise your specific contribution and how you collaborated with others.

2. 10

   Give an example of a time you had to learn a new process or tool quickly. How did you go about it?

   Show initiative: mention self-study, asking mentors, hands-on practice. Highlight the outcome and how it helped the team.

3. 11

   How would you handle a situation where a production operator disagrees with your proposed process change?

   Demonstrate respect and communication: listen to their concerns, explain data and benefits, involve them in trials, and seek win-win solutions.

4. 12

   Tell me about a time you made a mistake in a project. What did you learn?

   Be honest, focus on learning and corrective action. Show you take ownership and improved processes afterward.

HR and Company Fit

1. 13

   Why do you want to work as a Process Engineer in the manufacturing sector, especially in a company like Finolex Cables?

   Link your interest in process optimisation and hands-on work to the company's products and growth. Mention specific aspects like cable manufacturing or continuous improvement culture.

2. 14

   Where do you see yourself in five years in this role?

   Show ambition but stay realistic: e.g., grow into a senior process engineer or lead continuous improvement projects. Align with company's career path.

3. 15

   How do you prioritise safety and quality in a fast-paced production environment?

   Emphasise adherence to SOPs, proactive hazard identification, and balancing speed with quality checks. Give an example if possible.

4. 16

   Are you willing to work in shifts and at plant locations?

   Be honest and positive. If flexible, express willingness to adapt and learn from shop-floor exposure.
