You are taking to pilots at job fairs, and not HR, and that was over 10yrs ago, kind of what I thought. Sure, they'll "walk in your résumé", and that's likely how it worked back then, but they have a lot more to lose these days, as people are connected and able to share information, like on this website. The job fair thing is more about their pr and generating resumes on the website for HR to screen, IF they actually need anyone at the moment, otherwise it's just help with using the website and answering "do I qualify?" questions.

The reality is people are scrambling over each other to get major airline jobs. You might have 4000pic, someone else has 3500, 3 types, maybe the type needed, was a company check airman, captain of the football team, and has a seaplane rating. There are a lot of pilots that qualify, more than will ever get the job.
