Pluspunten
Good people to work with. No more typical bureaucracy and delays to get things done than any other large publicly-traded company. Very tight security controls. Have staff solely dedicated to acquisitions, so growth is a constant mode of change. Nepotism is not allowed so at least it's not one of "those" companies.
Minpunten
Typical bureaucracy and delays to get things done, so less nimble than a smaller privately-owned company. Very tight security controls, best plan to keep your personal Internet use to your own devices and Internet connection. Use this company to grow your resume if you need to, but keep looking for something else; I personally saw several people with well over 10-15 years get handed layoffs with very short notice.
