Ahem, “secured”.
Fun fact, pilot recruiting isn’t really able to keep the resumes, but are able to make notations notes and keep THOSE but not the actual resumes because of some legal reason.
What they’re generally supposed to do is record the name, notes and anything else to identify you in the system and then “secure the document” privately after the career fair.
Most medium and large companies won’t accept resumes outside of some formal process, but airlines will generally capture contact data, whether or not to move the applicant further into the process and then, 100% of the airlines will shred the document so your personal information doesn’t fly away in the wind when someone opens the convention loading dock door.
They did you dirty by showing you what’s behind the screen.
