The thing making me want out is having to change jobs every few years not to fall way behind on current pay, and having, for interviews, to prep for a series of goddamn pop-quizzes in a high-pressure environment, which could cover material from any or all parts of your education or career, plus a bunch of stuff you may well never have encountered in either, at practically any difficulty or granularity level, with, usually, no way to narrow the field you need to prep for down meaningfully even if the roles you're applying for are pretty specific, and usually with no clear understanding of how your performance will be judged. It's the only thing I've encountered in adult life that gives me stress-dreams like school did. "Normal" job stress, even when shit's on fire, is about 10% as stessful, at worst. I hate, hate, hate it.
