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.
...well now I made myself sad. Good job, me.
