Good on you. I left my post-university defense job after a year and a half. Of all career decisions, that's one I don't regret, and rather the regret I harbor was for joining in the first place (albeit did so under a combination of limited information & naivete).

The 'will not' list in here I Just learned about today, https://www.solzhenitsyncenter.org/live-not-by-lies it easily maps to the employment situation question.
