Hang in there buddy. I'm feeling your pain. I recently blew the virgin interview, compass (test) and got the Skywest job. 10 years later, 2 furloughs and 6 years at another regional I'm back to square one. But that's the name of the game.
I have found in this journey that the more "touchy- feely" you are with your interviewer, better the odds. However easier said than done. Remember they want to see the whole package not just your serious pilot side.
