General aviation, commercial, cargo, and military industries serving aviation each have their own unique brand of jargon, buzzwords, and keywords. Scouting out in advance in the form of more-than-cursory searches online can be what gets your resume picked up by a robot resume reader.
When applying online, there’s almost nothing more preeminently worth addressing than getting past the robot gatekeeper. Familiarizing yourself and being smart before tailoring your resume and applying are often worth it just for this reason alone.
Similarly, when applying in person, you need to catch your readers’ eyes. This should mostly be done through verbal conveyance. However, it’s worth noting that even the best personal interaction can’t save an awful resume.
