ability to interpret incomplete technical drawings and make sound judgment calls independently

Tell me about a time you caught a quality problem in your own work or someone else's before it moved down the line.

Have you worked in a union manufacturing environment before? What was that like day to day?

systematic troubleshooting ability on power, lighting, or instrumentation circuits

Technical

Walk me through your experience with drilling, reaming, countersinking, and riveting on sheet metal assemblies. What kind of parts were you working on?

whether hands-on experience matches the core fastening and hole-prep tasks in the job

Have you set up or operated shot peen equipment for stress relieving parts? What did that process look like?

Describe a time you installed a press fit or force fit bushing. What tools did you use and how did you know it was seated correctly?

practical knowledge of precision fit tolerances and self-checking work quality

What experience do you have with wire bundles, whether that's cutting, stripping, soldering, or installing them into an aircraft or mock-up?

exposure to the electrical assembly portion of the role, which is distinct from structural work

Describe your experience, if any, working as a quality inspector. What did you check for and how did you document it?

whether the candidate brings the preferred inspection background, since this role sits inside the quality-focused mechanic track

Situational

Say you're mating two major assemblies and you find a buckle or wrinkle in the outer skin that shouldn't be there. What do you do?

whether the candidate stops and corrects defects properly instead of covering them up or ignoring tolerances

If you were assigned to a shift or task you didn't expect, how have you handled that kind of change in a past job?

flexibility and willingness to work any shift as required by the union agreement

This job requires the ability to get a U.S. Secret clearance, which means U.S. citizenship and a clean background. Is there anything in your history that might be a concern there?
