Pros
You gain experience of what a place looks like with really poor management.
Cons
The company and senior management are stuck in the eighties. They will try to be relevant by using terminology (anybody hear about cloud and API's lately?), but they have no clue what they are doing. Then there's the thing where the entire company is now basically run by a single person (a large multinational with the same person as CFO, COO and CEO isn't alarming at all!). They absolutely refuse to listen to employees, but as with everything else, they will pretend to. Real experience: they were doing kick-off sessions, asking employees to submit questions which would be answered on-stage. Surprisingly, some questions actually made it to the app, but they were all deleted before the event. Everything is censored, there is absolutely no way that you can have an open and honest conversation with senior management.
