When tensions have subsided and tensions ease, I’d be concerned about the possible negative consequences we all need to work towards preventing. In the event of positive intentions, but reinforcing harm, I would ask the ethics board to inquire the systemically ways that employees could be provided with better safety training and prevent future occurrences by keeping the incident under wraps. Responsibility shouldn’t be equated with punishment in situations where lives are at stake.
22. If You Discovered A Potential Mass Reduction Modification That Could Enable Heavier SpaceX Payload Capacity, What Next Steps Would You Take?
Example Answer: Recognizing the immense upfront testing requirements and risks for any change in rocket design I’d arrange time with my leadership team to present my concept at a high level and request initial feasibility guidelines for conducting formal engineering assessments.
If given the green light to elaborate proposed changes I’d gladly make precise static and fluid flow models that show the anticipated lift increases, and indicating the points of containment that require the physical testing.
I’d also provide a prioritized list of next steps to be taken for quantified capability validation, focusing on security.
23. Tell Me About A Time You Failed At Something. What Did You Learn From That Experience?
Example Answer: As an intern assisting with Merlin engine modifications I messed up recording the disassembly process of the test component. After the team had reassembled the component for further examinations they noticed that it was not in the torque specifications and needed to take it apart completely again – making it impossible to evaluate the component for 2 days.
I was able to recognize the importance of clear process for smooth transitions within engineering teams.
