Pros
I believe the CEO to be a highly ethical person who cares about employees. Benefits were decent, and the job I had was one where I could show up, put in little effort (after repeated attempts to contribute more were dismissed as 'not my job'....see 'cons'), have no one notice my boredom, and get paid. If you are looking for job security over opportunity, this might be the place for you. Most of my co-workers were lovely people and many were happy working there--just depends on your priorities. Conservative management means they move very slowly on drastic changes.
Cons
My seven years there were basically career suicide, concealed from me by the illusion of opportunity. If you are talented, hard working, ambitious, creative, etc...do not expect anyone to notice (though you might get a 'gold star' literally) and plan on self-promotion if you want to get anywhere or learn anything new. If you are mobile/willing to relocate it might help. Technology is not cutting edge so depending on your position, you may be in for headaches there. Job security at the branch office where I worked was somewhat dependent on biting your tongue and not making waves, even when there was a real problem. At my office, people were sometimes promoted because of seniority or other office politics over talent or qualifications.
