Pros

I guess the pay is average/decent

Cons

This is the most hostile work environment I have ever experienced. Management bullies employees and other leaders know and do nothing about it. The place is so toxic and stuck in old school thinking and leadership only cares about boosting their own egos rather than doing good work

Great people. Decent Salary. Location was good. Interview process was fine.

Constant Layoffs, getting rid of the people who actually know how to do the job. Very chaotic environment.
