Pros
Brilliant if you love steering groups and no accountability. Some good people Decent chances for progression if you're in the right role and are friendly with the right people.
Cons
After a while it feels like you've fallen into a pit of despair that you'll struggle to climb out of. Once promising young professionals quickly become empty shells unrecognisable from when they first started. The old guard are empowered to grind new blood into the ground. People are given managerial roles because they've been around a long time, not because they're actually suitable for management. Often they're the least suited to it and nothing gets done about it. The politics.. Jesus christ the politics. If you think the back stabbing and bullying in Game of Thrones was bad, you've seen nothing. It's a constant battle just to navigate the political landscape in the company, everything needs a play, a plan, collusion with the right people so they'll "buy in". Complete lack of transparency over salaries, opportunities and benefits.
