I can count on both hands the number of people I know currently with CJOs from Delta, all of which have near identical qualifications and backgrounds as I do. Do I get the recommendation to have your app reviewed, 100%. But I’m willing to bet Hitch18 is the same way, and TBH it’s just easier to reference someone’s app who already had it scrubbed. I say this because that’s what I did, and actually found just a single mistake in the app I used, and the guy already works for Delta so HR didn’t catch it either. It worked for me; not saying it will for everyone, but the offer was made to me by my peers, I’m sure many others out there will do the same thing. I saved my money for interview prep.
