• 9. What is your experience with materials and their properties?
  A: I have a strong understanding of different materials and their properties. I have experience working with metals, plastics, and composites and know how to select the most suitable materials for a specific design.
• 10. Can you discuss a time when you had to innovate a solution for a design problem?
  A: In one project, the design requirements called for a specific mechanism that was not readily available. I researched different options and came up with a creative solution that not only met the requirements but also provided added functionality and cost-savings for the client.

Behavioral Questions

• 11. Tell me about a time when you had to work under tight deadlines.
  A: In my previous role, I was assigned to a project with a short deadline. I managed my time effectively, prioritized tasks, and communicated effectively with my team to ensure we met the deadline without compromising the quality of our work.
• 12. Can you discuss a successful project you have worked on and your role in its success?
  A: One of my most successful projects was a new product design that received positive feedback from clients and increased sales for the company. My role was to lead the design team, communicate effectively with other departments, and ensure timely delivery of a high-quality product.
• 13. Have you ever faced a challenging or difficult team member? How did you handle it?
  A: Yes, I once worked with a team member who consistently missed deadlines and had a negative attitude. I approached them personally, addressed their concerns, and provided support to help them improve their performance. We were able to mend the relationship and successfully complete the project.
• 14. Tell me about a time when you had to make a difficult decision in a project.
  A: There was a project where we encountered an issue late in the development phase that would significantly delay the timeline. I made the tough decision to redesign a specific component, which took extra time and resources, but ultimately save the project from being delayed.
• 15. How do you handle feedback and criticism?
  A: I view feedback and criticism as opportunities to improve. I listen attentively, reflect on the feedback, and use it to make necessary adjustments to my work. I also seek feedback from others to ensure I am constantly improving in my role.

Situational Questions

• 16. What would you do if a client requested a change to the design that goes against initial requirements?
  A: I would first discuss the requested change with the client to understand their reasoning and if there is a valid need for it. I would then assess the impact on the project and consult with my team to find a balanced solution that meets the client's needs and stays within the project's scope.
• 17. How would you handle a situation where a supplier delivered faulty materials for a project?
  A: I would work closely with the supplier to address the issue and find a solution. This could include requesting a replacement, negotiating for compensation, or finding an alternative supplier. I would also communicate with my team to find a workaround in the meantime to minimize any delays.
• 18. What would you do if you discovered a design flaw in a product during the testing phase?
  A: I would immediately report the issue to my team and identify the cause of the flaw. I would then come up with potential solutions and test them to find the best way to fix the issue without affecting product launch timelines.
• 19. If faced with conflicting project priorities, how would you determine which to prioritize?
  A: I would first consult with my team to understand the impact of each project and identify if there is any flexibility in the timelines. I would then prioritize based on the project's importance to the company, client, and any potential consequences of postponement.
• 20. What would you do if you were assigned a project outside of your expertise or experience?
