Pros
Decent benefit policies is the only I can think of.
Cons
Extremely old school and political environment. People are keeping their heads low and would rather opt to not bring up constructive ideas since those tend to backfire. Leadership team is unable to foster true innovation in the company so to improve EPS they largely rely on cost-driven acquisitions that typically result in thousands of laid off employees, constant reorganizations, and slowed growth of acquired companies. Some high management roles are held by people that would never pass the sniff test in other companies. If you are already there, get the big company name on your resume and get out as fast as you can after a year. You are loosing valuable time for your career and learning bad habits at this organization.
