Vantaggi
You got what you put in and I didn't personally see any favoritism. Very open management team who responded to feedback and was willing to answer tough questions. They sought to better the employee's experience within the constraints of corporate parent. Greatly improved flexibility over my last two years there. After proving yourself there is good upwards and sideways mobility. Lots of change and variety in projects. Good inter-departmental relationships on the whole.
Svantaggi
High expectations for everyone meant the work atmosphere could be quite intense at times. Management style can seem draconian depending on your role/tenure which can grate with some people (it didn't me as I had 'grown up' with it). Salary only competitive to a point and past that raises for non-management track took a lot of convincing.
