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 school project or coursework where you had to build something from scratch and test it before calling it done.

whether the candidate treats testing as part of building software, not an afterthought

Describe a time you had to troubleshoot something that broke and you weren't sure why at first.

debugging discipline and patience under uncertainty

Tell me about a group project where the requirements weren't fully clear at the start. How did you and your teammates figure out what to build?

comfort working with cross-functional stakeholders on ambiguous requirements

Have you ever worked in an agile setup, with sprints or standups? What did you find useful or frustrating about it?

familiarity with agile practices and self-awareness about team dynamics

Tell me about a time you had to learn a new tool or technology quickly with little guidance.

self-direction and learning speed, since this internship expects fast ramp-up on Ignition

Technical

Have you worked with Ignition or any SCADA/HMI platform before, and if not, what have you done to learn about manufacturing software systems on your own?

honest assessment of hands-on exposure versus willingness to self-teach in an unfamiliar niche

Tell me about a time you used Python, JavaScript, or SQL in a project. What did you build and what part was hardest?

depth of real coding experience versus surface familiarity with the languages listed

This role sits inside a manufacturing environment where software controls real production processes. Why does that context matter for how you'd write and test code differently than a purely web-based app?

whether the candidate grasps that mistakes in industrial software have physical, costly consequences

What does quality mean to you when you're building software, and how do you check for it before you consider something finished?

personal standards and process for verifying work, not just relying on others to catch bugs

Situational

Walk me through how you would approach building a new application in Ignition if you had never used the platform before.

how the person breaks down an unfamiliar tool into a learnable process rather than freezing

If you were asked to write a test script for an application you didn't build yourself, how would you figure out what to test?

understanding of QA fundamentals and reading unfamiliar code or requirements

Suppose you're partway through building a feature and a developer on the team tells you the requirement changed. What do you do next?

adaptability and communication when priorities shift mid-task

If you noticed a bug in an application that's already running on a factory floor, how would you decide whether to fix it immediately or escalate it first?

judgment about risk and communication in a live manufacturing setting
