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
This team is international and works with Caterpillar and Trimble product teams. Tell me about working across time zones and companies.
What they are checking: Communication habits that keep testing moving when teammates are not online at the same time.
Tell me about a bug you found that others had missed. How did you find it?
What they are checking: Curiosity and investigative habits that make a tester valuable beyond running scripts.
What would you do
You find a defect a week before release, and the product team says it is too minor to fix. How do you handle it?
What they are checking: Whether they can assess and communicate customer risk clearly instead of either caving or blocking blindly.
Your automated tests are flaky and the team has started ignoring failures. What do you do?
What they are checking: Whether they protect trust in the test suite by fixing root causes of flakiness.
How would you test a GNSS-based guidance feature when you cannot take a dozer to a job site every day?
What they are checking: Creativity with simulation, recorded data and test rigs for positioning products.
About the work
CTCT builds machine control products for earthmoving, paving and mining. How would you approach test automation for software that runs on a machine rather than in a browser?
What they are checking: Whether they understand embedded and hardware-in-the-loop testing, not only web UI automation.
Walk me through a test automation framework you designed or improved. What choices did you make and why?
What they are checking: Real framework design experience, including maintainability and reporting, not just writing scripts.
How do you decide what to automate and what to keep as manual verification and validation testing?
What they are checking: Judgment about where automation saves effort and where human checking still finds the important problems.
How do you write a good test case from a requirement that is vague?
What they are checking: Skill at turning unclear requirements into testable conditions and asking the right questions.
What programming languages have you used for test development, and how do you keep test code clean?
What they are checking: Whether they treat test code with the same care as product code, as the posting's software duties suggest.
