Vantaggi
The products are cool and there are some big name clients. Some people see great development opportunities. Money isn't skimped for things like travel or Friday drinks.
Svantaggi
Worst place I have ever worked. The CEO is completely toxic, other management figures enable his behaviour, and any staff lucky enough to not be in his firing line keep their heads down and ignore what's happening to their colleagues. Once he has randomly decided that he doesn't like someone, he will pick holes in their work in front of everyone, exclude them from the wider team and do anything he can to force them to resign, before taking more official measures if they won't. This has happened to enough employees to suggest that the problem lies with him, not them.
