Everything else.
A lot of people who've worked or work here feel like they've come from somewhere worse and have got the sense that this place will be better. It won't, for your own mental health, do not consider working here unless you're an expert at taking your lumps for failings you never knew about but were expected to, or enjoy being gaslit and discovering a new sense of imposter syndrome.
Completely clueless direction; constant reprioritisation; get used to being told to do things in conflict with your own experiences; "we have technical debt" is a gross understatement implying that there's a legitimate goal to improving this; false promises and statements in the interview process; gaslighting when doing work; unclear task requirements and deliverables. Endless changing and shifting of priorities and not focusing on the massive issue that every new starter has questioned shortly after joining. Strong sense of a controlling leadership who both expect others to organise things, but then wrest control over the top and fault others for it.
Only hiring experienced developers in some attempt to think its more skilled staff they need to solve the problems coming from leadership level.
"It used to be worse", a phrase uttered like a mantra. Attrition has been so high that knowledge on the product as a whole is concentrated into 1 person who you will quickly identify as a source of conflict.
