Second was waterfall dictatorship, mixed with "talent management" requiring managers to fire people every year, mixed with legacy shit that would never get funding to be fixed.
Third (now) is a mismatch between what I signed up for in scope and manager (both got changed shortly after I joined), incompetence of product management, lack of belief for what we are building, and no interest to our proposal of pivoting to something actually crucial and meaningful. We see the forest in fire with dinosaurs attacking leprosic people, we're volunteering with extinguishers, machine guns, and arm long firefighting/dinosaur taming/medical qualifications, and the only answer I get is "oh cool, throw glasses of water at the fire after work, but please do focus on building the new community center in the middle of nowhere".
There's a lot of admin, a lot of meetings, but I could cope with that if at the end of the day what we're working on was meaningful
