Pros
Presidio provided great opportunity to work on demanding and complex projects. Many of the engineering staff are very competent and there is great collaboration and growth among the teams. Presidio has a good reputation for being able to deliver on projects, particularly around Cisco.
Cons
While Presidio has for the most part maintained its reputation for technical competence, the leadership culture has changed dramatically. In the past it was a great place to work and the executive leadership was engaged. Today's executive leadership is distant from the people and is either disinterested or not capable of really engaging with the people that get the job done. The corporate CTO is an exception to this. Most real people leadership in the organization is at the first line of management or among peers.
