I know a whole bunch of guys in the same boat as you. I'm basically there myself; got all the stats and quals but only ever got called by UPS and I think that was just a lot of lucky timing (I did a lot more than 10 yrs at a regional too). Don't mistake the value of being young/moldable as being better at what we do. It's not. But for successfully integrating at a new company it apparently is. Nothing personal, just business. Dont give up, at least not yet.
