Im new to 121 pax flying and I see plenty of cpts releasing the brake early.
I feel for you. Honestly dont see 2 checkride busts years ago being a big deal, thats how you learn. Sucks hiring is still hyper competitive and thats the discriminator.
Hopefully you get a call, good luck
On a side note, I have a friend with a felony (stole a car) from 25 yrs ago get hired by 3 legacies recently. Thought he would never get a call but he finally did and all within 2 months of each other
