Behavioral

Tell me about a time you had to enforce safe operation standards in a test cell environment where people were under pressure to hit a deadline.

real commitment to safety culture versus lip service when schedule pressure hits

Describe a failure investigation you led on an engine durability or performance issue. How did you find the root cause and how confident were you in the fix?

rigor of root cause methodology and whether they own outcomes rather than just closing tickets

Tell me about a time you had to build or rebuild trust with a team of engineers and technicians after a period of disruption or turnover.

people leadership skill in a technical, hands-on team, not just program management

Tell me about a capital plan or budget you built for a lab or test facility. What did you have to cut or defend?

experience owning capital planning decisions, not just running day to day operations

Tell me about a time you managed an external test partner or supplier who wasn't meeting expectations. What did you do?

vendor management skill, since the role explicitly includes managing external test partners

Technical

What is your experience with engine dynamometers, emissions benches, and data acquisition systems, and where have you had to push the capability of that equipment?

depth of hands-on lab equipment knowledge versus purely managerial background

What is your experience working in EPA, CARB, or EU regulated certification environments, and how did that shape how you ran testing programs?

actual regulatory exposure versus general engine testing experience

How would you approach setting up standard work and data quality practices in a lab that has been running on informal, tribal-knowledge processes?

ability to institute engineering discipline and consistency, a core stated responsibility

Describe your experience with gasoline, natural gas, propane, or alternative fuel engines specifically. Where does your depth stop?

honesty about fuel-type breadth versus overselling generalist ICE experience

Situational

Walk me through how you would stand up an engine development lab organization from where it is today to where the roadmap needs it to be. What do you build first?

whether the candidate can sequence org, capability, and capital investments rather than jumping straight to hiring

Say your team is behind on validation milestones for a program executive leadership is watching closely. How do you communicate the risk and what tradeoffs do you offer them?

comfort translating technical risk into executive-level tradeoff conversations

If Engine Design wants to accelerate a validation timeline but your lab's throughput can't support it without cutting corners on data quality, what do you do?

willingness to push back on cross-functional partners to protect data integrity

How do you coach a strong individual contributor engineer who has the technical chops but struggles to mentor junior test engineers?

whether they can develop technical talent into leaders, since the role requires mentorship at scale
