3. How would you go about designing a new product if you did not have access to the materials or processes needed to manufacture it?

This question can help the interviewer understand your creativity and problem-solving skills. Use examples from previous projects to show how you would overcome this challenge.

Example: “If I did not have access to the materials or processes needed to manufacture a new product, I would start by researching existing products that are similar in design and function. This would help me understand what materials and processes are typically used for this type of product. Once I had an understanding of the materials and processes required, I could then begin designing my own product using those same materials and processes.

I would also look into alternative materials and processes that may be more cost-effective or efficient than the traditional ones. For example, if the traditional material is expensive, I might research other materials that can provide the same level of performance at a lower cost. Similarly, if the traditional process is time-consuming, I might explore ways to streamline it with modern technology.”

4. What is your process for testing a new design before moving forward with production?

The interviewer may ask you this question to understand how you apply your engineering skills and knowledge to test a design before moving forward with production. Use examples from past projects to explain the steps you take when testing a new design, including how you use data to support your decision-making process.

Example: “My process for testing a new design before moving forward with production is comprehensive and thorough. First, I create a prototype of the design to ensure that it meets all safety requirements and specifications. Then, I conduct extensive simulations and tests to evaluate the performance of the design in different scenarios. Finally, I review the results of these tests and make any necessary adjustments to the design. Once I am satisfied with the results, I move forward with production.

I have been working as a Senior Mechanical Engineer for over 10 years, so I understand the importance of quality assurance when it comes to designing and producing products. My experience has taught me how to effectively test designs to identify potential issues before they become costly problems down the line.
