Upper management was willing to hear ideas and opinions from non-management employees. There was a fair amount of freedom with how to shape your role and get your job done. Also, they were fairly openly to new ideas to help the organization.
Svantaggi
Glass ceiling for sure. Saw a lot of latent sexism that refused to be addressed by the then-President (I think he's gone now). I also left during a transition so I don't know about the current management at all.
