Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a defect you found late in a release. How did you decide whether it should stop the release?
What they are checking: Whether they can weigh severity and customer risk honestly instead of treating every bug as equal.
This team spans Caterpillar, Trimble and CTCT, across several countries. Tell me about a time you had to get a fix from a team you did not report to.
What they are checking: How they get results through influence when they have no authority over the people who own the fix.
The posting mentions resolving issues regarding design or manufacturing. Tell me about a problem you traced back past the software into hardware or production.
What they are checking: Whether they follow a problem to its real root cause even when it leaves their own area.
What did your last verification and validation role teach you that you would bring here on day one?
What they are checking: Whether they can name concrete, transferable lessons, since this hands-on role expects prior V&V experience.
What would you do
Our customers run machines in earthmoving, paving and mining. How would you test software for conditions you cannot easily recreate in a lab, like dust, vibration or poor GPS signal?
What they are checking: Whether they think about real jobsite conditions and know how simulation and field testing fit together.
A product manager wants to skip a regression cycle to hit a ship date. What do you say?
What they are checking: Whether they can push back with risk data and offer options rather than just saying no.
You get a field report from a paving customer that you cannot reproduce in the lab. What do you do next?
What they are checking: Whether they gather logs and conditions methodically instead of closing the issue as cannot reproduce.
About the work
Walk me through how you would build a verification and validation plan for a new grade control feature on a dozer, starting from the requirements.
What they are checking: Whether they trace every test back to a requirement instead of testing whatever seems interesting at the time.
What is the difference between verification and validation, and can you give me an example from your own work where something passed one and failed the other?
What they are checking: Whether they understand that building the thing right is not the same as building the right thing.
How do you write a bug report so a developer in another time zone can reproduce it without asking you a single question?
What they are checking: Whether their written communication is precise enough to keep work moving across an international team.
Which parts of a test suite would you automate first, and which would you keep manual on purpose?
What they are checking: Whether they choose automation based on value and stability instead of automating everything because they can.
How do you test software that talks to sensors and controllers over CAN or a similar bus?
What they are checking: Whether they have hands-on experience with embedded and machine control systems, not just web or app testing.
