I recently interviewed at Kalitta
It was last month and they brought in 12 of us from Puerto Rico to Honolulu. We paid our way, they covered two nights. Guys in training we met at breakfast said they were 50 crews (100 pilots) short. Training department said the same thing. Both said: "Don't crash the Sim on Day 2 and you'e hired".
Day One: Our group was a mix of military, corporate, and 121 guys and 3 women. We all took a modest "Aptitude" test and had a panel interview where the body language said no one wanted to be there.
Each of us was given a "Thanks but no thanks" letter as we departed. No one was taken to the sim'. Friends on the inside were blown away by this. Any input would be appreciated. Otherwise, it was a cordial and professional experience.
