Pros
Health insurance is pretty good and covers some alternative medicines. Office dress code is nonexistent unless you are going to offsite meetings. The smaller departments have big career building opportunities and many of the older employees are beginning to retire and create a promotion vacuum.
Cons
Offices are out of date cube farms with little sunlight or windows. Hours are rigidly fixed from 8am-5pm with an hour lunch at noon at most offices except for a few smaller independent departments that allow flex schedules. Sick and vacation time are separate benefits and sick time is very difficult to use. You can't cash out your sick time either, so after a few years you max out on sick hours and stop accumulating them all together. Vacation time is limited to 2 weeks a year for your first 5 years and must be accumulated before being used. No location adjustment is made to salaries even if your home office is in an expensive city or region. No company stock options unless you are one of the golden children and have been at the company for a long time.
