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 your simulation results disagreed with what a colleague or test engineer expected. How did you handle that conversation?
ability to defend technical findings and navigate disagreement without being dismissive or capitulating
Give me an example of when you had to present complex simulation results to someone without an engineering background. What did you cut out and what did you keep?
ability to translate technical detail for non-technical stakeholders, called out explicitly in the posting
Tell me about a code design review that didn't go well. What happened and what did you change afterward?
self-awareness and whether they actually learn from cross-functional friction, not just avoid it
What's an example of a documentation format or standard reporting practice you've used or helped build, and why did it matter?
whether they take documentation seriously as part of the job, since it's called out as a duty, not an afterthought
Technical
Walk me through a time you built system-level engine control code in Simulink for a gaseous fueled engine. What was the architecture and what were you trying to control?
whether the candidate has hands-on depth building real Simulink models for engine control, not just theoretical familiarity
Tell me about your experience with SAE J1939 CAN networks. What kind of fault codes and SPNs have you worked with, and how did you use that data?
real exposure to the specific communication protocol and diagnostic standards named in the posting
Have you set up a Software-in-the-Loop or Hardware-in-the-Loop environment before? Tell me about one and what problems it caught before hardware testing.
depth of co-simulation experience versus just knowing the acronyms
Describe a project where you used ATI Vision to set or adjust calibrations. What were you calibrating and how did you know it worked?
whether ATI Vision experience is genuine and applied, since it's named specifically in the posting
Explain how you'd apply machine learning or predictive analytics to forecast engine performance or emissions. What data would you need and what would trip you up?
whether ML familiarity is real and grounded in engine data realities, not buzzword-level
What automotive standards have you had to design or test against, and how did they shape your approach to code validation?
real familiarity with automotive standards mentioned as a requirement, not just a checkbox
Situational
Say you've got an engine that's stable at steady state but oscillating during transient load pickup. How would you go about diagnosing and fixing that in code?
practical troubleshooting approach for transient performance issues, a core job duty
If you inherited an existing Simulink codebase for engine control with no documentation, what's your first move before changing anything?
discipline around understanding legacy code and risk before modifying safety-relevant control systems
Tell me about a time you had to balance getting a result fast against getting it fully validated. How did you decide where the line was?
judgment about rigor versus speed in engineering validation, relevant to a senior individual contributor role
