Pros
You will learn very quickly what a dysfunctional workplace looks like.
Cons
The company has a serious overtime culture and a highly political working environment. Staff are often expected to stay late because it became a norm to be seen as such, otherwise you're the target. People are pretending to work just to stay late. There is also a strong blame culture, instead of proper leadership and accountability. The internal politics are not limited to management. It can also spread across teams, creating an environment of highly political, lies spreading, blaming, credit stealing than actually working professionally like a proper adult. The female boss also show poor emotional control and low workplace maturity. This is not a healthy place for long term growth.
