KEI Industries Process Engineer Interview: Rounds, Questions and Preparation

What the job involves

Process engineers in manufacturing, automobile and engineering sectors design, optimise and monitor production processes to improve efficiency, quality and safety. They work on the shop floor and with cross-functional teams to reduce waste, troubleshoot issues and implement continuous improvement projects. At companies like KEI Industries, they may focus on cable manufacturing, extrusion, winding or assembly processes.

Role and Technical Knowledge

1. 1

   Explain the difference between process engineering and production engineering in a manufacturing setup.

   A strong answer distinguishes process engineering (designing and optimising the method) from production engineering (executing and managing the method). Give examples like cycle time reduction versus daily output tracking.

2. 2

   What are the key parameters you would monitor in an extrusion process for cable manufacturing?

   Mention temperature profile, screw speed, line speed, die pressure and cooling rate. Explain how each affects product quality like insulation thickness or surface finish.

3. 3

   How do you calculate process capability (Cp and Cpk) and what do the values indicate?

   Define Cp as potential capability and Cpk as actual capability considering centering. State that Cpk > 1.33 is generally acceptable for automotive and engineering parts.

4. 4

   What is the role of poka-yoke in process engineering? Give an example from automobile or cable manufacturing.

   Explain poka-yoke as mistake-proofing. Example: a sensor that stops the machine if the wire diameter is out of spec, or a fixture that only allows correct orientation of a connector.

Practical Scenarios and Problem Solving

1. 5

   You notice a sudden increase in rejection rate on an assembly line. How would you investigate and resolve it?

   Walk through a structured approach: define the problem, collect data, use Fishbone or 5 Why to find root cause, implement a countermeasure, and verify with a pilot run before standardising.

2. 6

   A machine has a cycle time 20% higher than the standard. What steps would you take to bring it back to target?

   Suggest time study, identify bottlenecks, check for tool wear, operator method, or material variability. Propose quick kaizen actions and then a long-term improvement like automation or fixture redesign.

3. 7

   How would you reduce changeover time on a cable winding machine?

   Mention SMED principles: separate internal and external activities, convert internal to external, streamline remaining internal steps, and standardise. Give a practical example like pre-setting tools or using quick-release clamps.

4. 8

   You are asked to improve energy efficiency in a molding process. What data would you collect and what changes might you propose?

   Collect data on cycle time, heating energy, cooling energy and idle time. Propose optimising barrel temperatures, reducing idle running, and using insulation blankets or variable frequency drives.

Behavioural and Teamwork

1. 9

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

   Use STAR format: situation, task, action, result. Highlight your specific contribution, how you handled disagreements and what you learned about teamwork.

2. 10

   How would you handle a situation where a production operator refuses to follow a new process change you implemented?

   Show empathy and communication. Explain that you would listen to concerns, explain the benefits, provide training, and involve the operator in refining the change to gain buy-in.

3. 11

   Tell me about a time you made a mistake in a project or experiment. What did you do?

   Choose a real, low-stakes example. Focus on how you identified the error, corrected it, and put a system in place to prevent recurrence. Show accountability and learning.

4. 12

   Give an example of how you prioritised multiple tasks under a tight deadline.

   Describe a situation from college or internship. Explain how you assessed urgency and impact, communicated with stakeholders, and delivered on time without compromising quality.

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 KEI Industries?

   Connect your interest in hands-on problem solving and continuous improvement to the sector. Mention KEI's reputation in cables and your desire to learn large-scale production. Avoid generic answers.

2. 14

   Are you comfortable working in shifts and on the shop floor? How would you adapt?

   Show willingness and maturity. Mention that you understand the importance of shop floor exposure for a process engineer and that you are ready to learn from operators and technicians.

3. 15

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

   Outline a realistic path: gaining expertise in process optimisation, leading small improvement projects, and eventually becoming a subject matter expert or team lead. Align with the company's growth.

4. 16

   What do you know about KEI Industries and its product range?

   Research key facts: KEI is a leading manufacturer of wires and cables, with products for power, control, and instrumentation. Mention its presence in India and abroad, and its focus on quality and innovation.
