I hire people and I read your Facebook, LinkedIn, etc. I also check with people who know you. There is a lot of truth to the saying, it is who you know. If you don’t know anyone and you put dumb stuff on your Facebook, adios resume.
While I don’t hire airline pilots, I have taught more of you than I care to think about. Always excites me when people post a video of them violating some FAR on Facebook.
Don’t be stupid, good luck!
