Pros
You can rise from entry level in this company if you're willing to fight for it. Even if you only have a liberal arts degree and knew nothing about insurance when you started. The insurance offered is good. Cheaper than most other employer plans and much cheaper than Obamacare. Great 401k with the 3% match and you can borrow from it once you're vested in 3 years. Insane amount of time off from the start, 18 paid days of vacation Really good senior leadership, especially the CEO, David Cordani, he and his team have done a lot to modernize this company from where it was at when I started in 2008.
Cons
Compensation is not great for those who do start at the bottom and rise through the company, you'll find you will be consistently underpaid compared to your peers at the same level who enter the company from the outside. Some people who use the insurance more than I do complain that it doesn't pay enough and the high deductible creates a lot of stress for them early in the year.
