I still, to this day, do not know what I did different at my AA interview that got me the job. I have my thoughts, but I'll never know for certain. One answer I gave might have been my savior even though I swore on that 2 hour flight from DFW to home, it was what did me in from not getting a day of CJO.
This was after my application/interview went to the review board before I was given a CJO a week later. Out of 13 people in my interview group, I was one of 4 who didn't get a CJO that day. The AA interview was the last one out of Spirit, Southwest, Allegiant, Breeze,Jetblue (which I waited out the pandemic to be told TBNT after a face to face) and I'm sure I'm forgetting one. I was bitter, I was angry at everyone moving on from the regional except me. And I was really pissed at myself for not being able to figure out WTF I was doing wrong. I don't interview well, that much was certain.
I don't know if the secret sauce changed (like what they were looking for credentials-wise), if I did something in my interview or phrased something better than I had been doing in my previous 5 attempts. I had done prep with 3 different companies. I spent big money (to me) having my electronic logbook professionally printed out and adding some personal touches when I got it back.
I don't know what I did, but I kept on going. It has been worth it on many levels and considering how some of the companies I interviewed with have gone, AA was the best one I could have done for a lot of reasons. It sucks, keep going, you'll get there. Somehow.
