Practice Questions

💡Technical Questions (3)
  • 1.Walk me through your approach to designing a catheter shaft that requires both high pushability for navigating tortuous anatomy and extreme flexibility at the distal tip.
  • 2.How do you structure the design verification and validation testing for a new minimally invasive device to ensure it meets both user needs and regulatory requirements?
  • 3.Describe your experience using SolidWorks for catheter design. How do you manage the complexities of modeling multi-lumen extrusions and braided shafts?
🎯Behavioral Questions (3)
  • 1.Tell me about a time you led the end-to-end development of a catheter-based device from concept to commercialization. What was your role and what was the outcome?
  • 2.Describe a situation where you had to balance being hands-on with technical problem-solving while also managing strategic project priorities for executive leadership.
  • 3.Give me an example of a time you provided direct leadership to a team of engineers and technicians on a complex minimally invasive device project. How did you ensure their success?
🧩Situational Questions (2)
  • 1.You are leading multiple high-priority catheter development programs, and executive leadership asks you to take on an accelerated timeline for a new minimally invasive device. How do you respond?
  • 2.During validation testing of a catheter, your team discovers a failure mode that was not anticipated during risk analysis, and the product launch date is now at risk. How do you handle this?
