Pros
A place where you can build up your technical knowledge and complete your training. Great colleagues that you will bond with given the severe working conditions. You can get a lot out of working at Chubb, but I'd recommend having a good therapist and a clear exit strategy in place.
Cons
They aren't able to hold on to good staff, or seem to really try to hold on to good staff. This results in a continuous status of being under-staffed, and the staff left over being overworked with the vague promise of it eventually getting better (which it never truly does because they work on a cycle where they are okay with letting people walk out because they get burnt out, and have no incentive to stay since they pay under what the rest of the market does). I found that Chubb does tend to keep people by convincing employees that their products is superior in the market, and that they don't need to participate in marketing, or spend money on taking brokers out to dinner or lunch, or anything else. They also convince employees that they were lucky to have gotten the chance to work there and so should be grateful and put up with prolonged periods of working 10++ days for weeks and months on end.
