Pros

- supportive teammates i guess - good HMO

Cons

- Inconsistent and poorly communicated company policies (not sure if it was all planned but all i know is that it led to significant career disruptions for many employees including mine) - excessive and unrealistic workloads resulted in widespread employee burnout and high turnover - they just don't know how to take care of their people overall
