In my first month 3 of my immediate team members went on mental leave and never came back. If this wasn't a bad enough omen, in the year since I've left almost my entire team has left the company.
Management is directionless, changing Main Business Objectives half way through the year, leading to reorganizing teams, eliminating jobs, and changing positions. Directors act like they are in Game of Thrones and try to steal each others projects and teams. This leads to team names being redundant and unclear. Middle managers fail at basic tasks like training, and meeting with their own direct reports. They also do not set goals, and then when you fail to meet whatever vision is hidden in their head they will throw you under the bus so that they don't look incompetent.
