Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
Behavioral
Tell me about a time you led a new technology concept from an early idea all the way through prototype and testing. What did that path actually look like?
whether the candidate can drive ambiguous early-stage work to a concrete technical outcome, not just manage a defined project
Give me an example of a system-level trade-off you had to make between cost, performance, and safety. How did you decide, and who pushed back?
ability to reason across competing constraints and defend a technical decision to stakeholders
Tell me about a time you had to coach or develop an engineer who was struggling, whether that was a direct report or someone you led informally.
real people-leadership experience versus purely technical management
Tell me about a project where the requirements were fuzzy and you had to define the test plan yourself. How did you decide what to measure and what good looked like?
comfort operating without a fully specified brief, which this NTI role demands
Tell me about a time you worked with an outside supplier or technology partner on something still in development. What went wrong and how did you handle it?
experience managing external partners through uncertainty, a named preferred qualification
Technical
Walk me through how you'd structure a technology readiness evaluation for a new battery chemistry or power electronics approach being considered for a portable power station.
understanding of structured feasibility and readiness-level thinking versus ad hoc testing
How would you integrate mechanical, electrical, controls, and thermal considerations when you're only at the concept stage and don't have full data yet?
depth of cross-disciplinary systems thinking specific to portable generator and battery architecture
Describe how you've used teardown or competitive benchmarking to shape a new product concept.
hands-on rigor and whether they actually do the grunt work of comparative analysis, not just direct it
How do you take a raw customer insight, something someone said in the field, and turn it into an actual engineering requirement?
whether they can bridge voice-of-customer input and hard technical specs
Situational
Say your prototype build is delayed because a supplier component didn't show up on time and your test lab window is closing in two weeks. What do you do?
practical prioritization and resourcefulness under real schedule pressure common in NTI work
If two engineers on your team disagree about which technology path to pursue and both have good data, how do you resolve it and keep the team moving?
decision-making style and ability to maintain team cohesion during technical disagreement
Suppose leadership wants a technology readiness decision in three weeks but your test data is only 70 percent complete. What do you tell them?
honesty and judgment when forced to make a call with incomplete evidence
You'll be splitting time between Waukesha and Jefferson roughly once a week. How would you keep a distributed team aligned on priorities and lab schedules across two sites?
practical plan for managing execution and communication across locations, called out explicitly in the posting
