"Not Accepted" -- If you know anything about industry or the world, you can't go through a listing of ten tech jobs, without immediately rejecting some jobs from consideration, because they're morally/ethically icky.
(Just yesterday, I paused, and then sent a recruiter notes on why I wasn't interested in a couple companies they'd selected for me. Not to be That Person, but because I wanted to help them find what's interesting to me, and also to invite them to push back if my initial assessment of a company was off.)
"Left a Job" -- This is much harder than not accepting/considering, but it also happens. A couple variations:
* I'm guessing the most common way might not be deciding that you have to leave because of something immoral, but you're forced out before then, because you don't play along with the immoral or whatever is leading up to it. (This reason could be coming across as goodie-two-shoes risk, or refusing to so some immoral thing, or actively working to reverse/prevent some immoral thing.)
* Something immoral might be going on, but there are additional reasons to leave. Such as (predictably) people behaving immorally wrt customers or society might also behave immorally wrt employees/colleagues. So you might leave because the work environment is hazardous, your coworkers are backstabby, or you were cheated out of a bonus... even before you decide that the business of kicking puppies is wrong.
