Pros

Salary was somewhat fair, however minimal bonuses / raises. Ultimately the toxic culture outweighs nearly every potential pro

Cons

- Poor people management and lack of accountability at the management level - Disrespectful communication from leadership, including being talked down to and undermined in front of others - Feedback culture feels punitive rather than constructive - Employees are not supported or treated with empathy during layoffs - HR processes are inconsistent and require excessive follow-up, essentially nonexistent
