Pros
You'll get a lot of experience you can sell to other employers. I never had trouble taking time off for vacation or going to a doctor. Everyone aside from upper management are amazing people. This includes the odd fact that middle-management was great, which is very uncommon in my experience. Some jobs are fulltime work from home.
Cons
Executive Leadership: A new CEO was brought in two years ago from Berkshire. He had never worked at the company and his background is that of an investment banker not a CEO. This has resulted in a lot of layoffs to make balance sheets look better. The people who weren't laid off quit in droves. The pay was always a little low, but the stability is gone so its no longer worth working at GEICO. The workload will be too much to stay on top of.
