I flew with lots of CAs at my regional who I considered to be great pilots and more qualified than me who hadn't heard anything from any airlines. BUT, they didn't do any of the 'extra' stuff like job fairs, volunteering, or even networking. They just submitted their app and didn't even update it that often (every few months). For comparison I interviewed at 5 different airlines (not bragging, just saying that it seems like job fairs and networking work).

I looked at the guys around me who were getting hired and they were 80% FOs or very recent upgrades who did a ton of the 'extra' stuff. It may not be right, but that's what I saw. I think I got the interview because I was able to have my app scored in combination with having a reasonably good resume.
