Greenko Quality Engineer Interview: Rounds, Questions and Preparation

What the job involves

A Quality Engineer in manufacturing, automobile, and engineering ensures products and processes meet quality standards and customer requirements. They use tools like root cause analysis, statistical process control, and inspection methods to identify defects, drive continuous improvement, and reduce waste. Day to day, they may conduct audits, analyze data, collaborate with production teams, and implement corrective actions.

Role and Technical Knowledge

1. 1

   What are the 7 QC tools and how have you used any of them in a project or internship?

   Name the tools (check sheet, histogram, Pareto chart, cause-and-effect diagram, scatter diagram, control chart, flowchart) and give a specific example of using one to solve a problem.

2. 2

   Explain the difference between accuracy and precision with an example from manufacturing.

   Accuracy is closeness to true value, precision is closeness of repeated measurements. Use a bore diameter measurement example to illustrate.

3. 3

   What is SPC and how do control charts help in a production line?

   SPC uses statistical methods to monitor and control processes. Control charts distinguish common cause from special cause variation, helping decide when to adjust a process.

4. 4

   What is the purpose of a PFMEA and how does it relate to control plans?

   PFMEA identifies potential failure modes, their effects, and causes, and prioritizes actions. Control plans then document the controls for those failure modes.

Practical Scenarios

1. 5

   You notice a recurring defect on an assembly line. How would you approach solving it?

   Use a structured approach: define the problem, collect data, analyze root cause (fishbone, 5 Whys), implement and verify corrective actions, and standardize.

2. 6

   A supplier sends parts that are out of specification. What steps would you take?

   Immediately quarantine the parts, inform the supplier, issue a SCAR (Supplier Corrective Action Request), and follow up with verification of corrective actions.

3. 7

   How would you handle a situation where production wants to ship a batch that has a minor cosmetic defect?

   Assess against specifications and customer requirements. If it is a deviation, follow the deviation process; if not, reject and explain the risks of shipping nonconforming product.

4. 8

   During an internal audit, you find that a calibration record is missing. What do you do?

   Document the nonconformity, investigate the impact on measurements, initiate corrective action, and ensure the calibration system is updated to prevent recurrence.

Behavioural and Situational

1. 9

   Tell me about a time you had to convince someone to change their approach to quality.

   Use STAR method: describe the situation, the resistance, how you used data and communication to persuade, and the positive outcome.

2. 10

   Describe a situation where you worked in a team to achieve a quality goal.

   Highlight your role, collaboration, and how you contributed to a measurable improvement or successful project completion.

3. 11

   How do you prioritize when you have multiple quality issues to address?

   Explain prioritization based on severity, impact on customer, and risk. Mention tools like risk matrix or Pareto analysis.

4. 12

   Give an example of a mistake you made and what you learned from it.

   Choose a genuine mistake, show accountability, and focus on the lesson learned and how you improved processes or yourself.

HR and Company Fit

1. 13

   Why do you want to work in quality engineering, especially in manufacturing?

   Show passion for problem-solving, continuous improvement, and the impact of quality on safety and customer satisfaction. Relate to your studies or projects.

2. 14

   What do you know about our company and how does quality fit into our operations?

   Research the company's products, markets, and quality certifications. Explain how quality ensures reliability and compliance in their sector.

3. 15

   Where do you see yourself in five years in the quality field?

   Show ambition to grow into roles like Quality Manager or specialize in areas like Six Sigma, while emphasizing commitment to learning and contributing.

4. 16

   Are you willing to work in shifts or at different plant locations?

   Be honest but flexible. Express willingness to adapt to business needs and eagerness to gain hands-on experience.
