Pros
Incredible career growth opportunities. Because of GEICO's growth, which has topped the industry for at least the last 10 years, there is a constant need for more people to move into management (and upward within the management ranks). The best part is that GEICO knows how to develop managers/leaders, and they're committed to doing it. I've seen so many people, who originally never thought about being in management, get the opportunity, get the development, and do extremely well. Stability like no other company I know of. Being wholly owned by Berkshire Hathaway (Warren Buffett), you know you are with a stable company with ownership that's in it for the long haul. During the last two recessions, I almost felt guilty about how great my career and the careers of those who work with me were going. In good economic times and bad, people always want to save money and get better service - that's what we do! Outstanding pay and benefits. Promoting from within is a staple of the culture here. Hardly anyone at any level of management didn't start out doing the entry level job. That's pretty rare in a company this size.
Cons
This would only be a "con" for some (I see it as a pro), but GEICO expects its associates to work hard. It's no harder than I was brought up to work anyway, but some people find it to be too hard. I love it because the days go by quickly and at the end of the day I feel like I earned my money.
