Pros

Company culture is relatively better compared to a lot of other companies in the same industry

Cons

Too many layers of middle management makes efficiency extremely low. A lot of groups are fighting for survival and the middle management is creating a lot of huddles to prevent people actually doing the work work more efficiently
