• Explain how you collect and analyze data during testing
• Detail how you interpret results to make recommendations for improvements
• Mention any relevant standards or regulations you follow during testing

What not to say

• Providing vague or generic descriptions of testing processes
• Failing to mention specific tools or equipment used
• Ignoring the importance of data analysis and interpretation
• Overlooking industry standards or safety regulations

Example answer

“In my role at Bosch, I developed a comprehensive testing protocol for spark plugs where I simulate various engine conditions by adjusting temperature and pressure settings. I utilize a dynamometer for performance testing and analyze ignition timing and combustion efficiency. The data collected helps me identify patterns that guide product enhancements. Following ISO standards ensures our tests are reliable and valid.”

Introduction

This question evaluates your problem-solving abilities and attention to detail, both essential traits for a Senior Spark Plug Tester responsible for quality assurance.

How to answer

• Use the STAR method to structure your response
• Clearly describe the defect and its potential impact on performance
• Explain the steps you took to investigate and confirm the defect
• Discuss how you communicated your findings to the relevant teams
• Share the outcome and any changes made as a result

What not to say

• Blaming others for the defect without taking responsibility
• Giving vague descriptions of the defect or investigation process
• Failing to explain how you communicated with the team
• Not discussing the long-term implications of the defect

Example answer

“At my previous job at NGK Spark Plug, I discovered a recurring issue with a specific spark plug that led to misfires. I meticulously documented the test results and conducted further tests under controlled conditions. After confirming the defect, I reported my findings to the engineering team with a detailed analysis. As a result, we revised the design to enhance durability, ultimately improving product reliability and customer feedback.”

Introduction

This question is important for understanding your technical knowledge and attention to detail in performing quality assurance tasks related to spark plugs, which are critical components in engine performance.

How to answer

• Outline the step-by-step process you follow when testing spark plugs
• Discuss the specific tools and equipment you use for testing
• Explain how you interpret test results and make decisions based on those results
• Mention any standards or regulations you adhere to during testing
• Share examples of how you have identified and resolved issues in the testing process

What not to say

• Providing vague details without a clear process
• Neglecting to mention the importance of quality standards
• Overlooking the role of collaboration with other team members
• Failing to give examples of past experiences that showcase your expertise

Example answer

“In my role at ACDelco, I follow a rigorous testing protocol that includes visual inspections, electrical resistance tests, and performance evaluations under various conditions. I use specialized equipment like digital multimeters and spark testers to gather data. Once I analyze the results, I compare them against industry standards to ensure compliance. For instance, I once detected a batch of spark plugs that failed to meet resistance specifications and worked with the production team to address the issue before they reached customers.”
