A bro of mine interviewed 4 times-got in on the 4th try. Small door closes over here means a larger door opens over there.
You might not see it now, because I know what the sting of a rejection letter feels like, but if I'd been hired by a "major" when I was trying so hard, I wouldn't be doing what I'm doing now-which is SSSOOOOOOOOOO much better.
Have a beer or three, shake out that gravel kit, and onward and upward.
