Here's the trick with the principles of networking, folks. It's important to get your name out there and meet the mover's and shakers, no matter what your experience level is.
If you shake hands, exchange business cards, and get your name out there, by the time that your qualifications match what they're looking for, you've already broken the ice, "pre-interviewed" and you'll be afforded an opportunity a lot of other pilots may not have had.
Most of the people that I networked with earlier in my career were at levels where they really couldn't help me. But as my experience grew, the people I met years before were able to assist me.
An example. I met a UPS 747 captain named Aaron Gould when I was a 500 hour CFI. He had a friend that was CEO of a small midwestern regional. By the time that I had regional minimums (at the time, roughly 1300-ish hours), I was already familiar with the movers and shakers at Skyway.
While I was at Skyway, I met a very helpful MD-88 check airman, Jay Bailey, at Delta but I had nowhere near the competitive minimums to apply, but we kept in touch. As my experience built and I reached competitive minimums, I was offered an opportunity to interview for a pilot position.
Networking starts before you even get your first hour of flight time. It's never too early. Hell, networking can even start with something as simple as registering for Jetcareers.com and asking lots of questions, presenting (and maintaining) yourself as a helpful member of the community and opportunities will present themselves.
