Pros
Because you are expected to do everything, you learn a lot.
Cons
Absolute worst work culture, hence an abnormally high attrition rate for employees within their first year. Turnover leads to ever-shifting strategy and planning discussions for projects that never actually make it to execution. Frequently encounter "not my job" syndrome where team's take advantage of the large bureaucracy to evade responsibility. External leaders are hired to be scapegoats for pre-existing organizational issues. Ethical issues are swept under the rug by HR. Impossible to get a word in during a meeting when many in the room just want to hear themselves speak. Senior leaders- shockingly- heed gossip and make decisions and promotions based on it.
