I was only at SkyWest for about a year. I flew with one captain who was really great. He was super negative about job fairs and moving on. He'd been to dozens of events, he had plenty of experience. Yet he couldn't get a call. He's sort of my reminder that no matter what you do, you may not be able to move on. He was not the "lifer" type but he was certainly stuck.
Two other captains stick out in my mind: one was convinced that the majors needed to call him. Since he'd been operating their flights for so long. I got a chuckle. Another was visibly upset when he found out I was moving on. I asked if he had applied during the last window. He had not.
I must say that my last line at SkyWest as a 175 FO had 17 days off and all really nice trips out of SFO. I'd kill for that schedule now and for PBS. But as one old timer said to me long ago: "make sure the check you get matches the paint on the airplane."
