I was like 90% of the way through the application process for apprenticeships with them (which took MONTHS) and I bailed at the very end when they required some surprise extra hoops to jump through that I didn't expect. I felt like I couldn't ask for that time off of work.
It was the wrong choice, and I knew at the time it was the wrong choice, but I was too frustrated and just walked away. I should have just quit that current job instead.
I'm really mad at myself about that, honestly.
And my partner tried really, really hard to convince me to finish the process and I was too upset to listen.
