Denso India Production Engineer Interview: Rounds, Questions and Preparation

What the job involves

Production Engineers in manufacturing and automobile sectors plan, monitor, and improve production lines to ensure parts are made safely, on time, and to quality standards. They work on the shop floor with operators, maintenance, and quality teams to solve daily problems, reduce downtime, and implement lean manufacturing practices. At companies like Denso India, they may focus on assembly, machining, or component production for automotive systems.

Role and Technical Knowledge

1. 1

   What is OEE and how would you calculate it for an assembly line?

   Define OEE as Availability x Performance x Quality. Explain how to measure each component using actual production data, downtime, and defect counts.

2. 2

   Explain the difference between push and pull production systems. Which one is used in automotive component manufacturing and why?

   Push is schedule-based, pull is demand-based (Kanban). Automotive often uses pull to reduce inventory and respond to customer demand.

3. 3

   What are the seven wastes in lean manufacturing? Give an example of each from an automobile production line.

   List overproduction, waiting, transport, overprocessing, inventory, motion, defects. Provide specific examples like excess parts between stations or operator walking to fetch tools.

4. 4

   How do you perform a time study to set a standard time for a manual assembly operation?

   Break the task into elements, observe and record times, rate the operator, apply allowances, and calculate standard time. Mention using a stopwatch and ensuring representative cycles.

Practical Scenarios

1. 5

   A critical machine on your line breaks down frequently, causing 20% downtime. How would you approach solving this?

   Use root cause analysis (5 Whys, Fishbone), review maintenance records, involve maintenance team, implement corrective and preventive actions, and track OEE improvement.

2. 6

   You notice that a batch of components has a dimensional deviation. What steps would you take from a production perspective?

   Stop production, quarantine the batch, inform quality, trace back to the process, check machine settings and tool wear, and implement containment and corrective actions.

3. 7

   Your line is behind schedule by two hours. How would you recover without compromising quality or safety?

   Assess bottlenecks, reallocate manpower, reduce changeover time, communicate with team, and possibly run a short overtime with approval while maintaining quality checks.

4. 8

   How would you implement 5S in a work area that has poor housekeeping and frequent tool misplacement?

   Start with sorting, set locations for tools, standardize visual controls, schedule regular audits, and train operators. Emphasize that 5S is continuous, not one-time.

Behavioural and Teamwork

1. 9

   Describe a time when you worked in a team to complete a project under a tight deadline.

   Use STAR method: situation, task, action, result. Highlight your specific contribution, coordination, and how you handled pressure.

2. 10

   Give an example of a time you identified a problem and took initiative to solve it.

   Choose a project or internship example. Explain the problem, your analysis, the action you took, and the measurable outcome.

3. 11

   How would you handle a disagreement with a senior operator who has more experience than you?

   Show respect, listen to their perspective, present data or facts, and focus on the common goal of safety and quality. Avoid confrontation.

4. 12

   Tell me about a time you had to learn something new quickly. How did you go about it?

   Describe the situation, your learning approach (asking questions, observing, practicing), and the result. Emphasize adaptability and eagerness to learn.

HR and Company Fit

1. 13

   Why do you want to work as a Production Engineer in the automotive manufacturing sector?

   Connect your interest in automobiles, manufacturing processes, and continuous improvement. Mention exposure to lean practices and desire to work on the shop floor.

2. 14

   Are you comfortable working in shifts, including night shifts, and in a factory environment?

   Answer honestly and positively. Show willingness to adapt to shift work as part of the role and mention any prior experience if applicable.

3. 15

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

   Show ambition to grow into senior production or process engineering roles, while emphasizing gaining deep technical expertise and contributing to the company.

4. 16

   What do you know about our company and why do you want to join us?

   Research the company's products, manufacturing footprint, and reputation. Link your skills and career goals to their work in automotive components.
