Pros

Good company. Strong pipeline. Culture is very different across the divisions. Overall good culture but better in some divisions.

Cons

Too much duplication and bureaucracy. Has slowed decision making and priorities can lack discipline. Promotions are limited. Preference to go to other roles rather than grow within role.
