Pros
Amazing benefits especially if you have a family. The salary is pretty good based on location, but not competitive when you look at any other company that employees actuaries. Decent work/life balance, they used to make us come in on weekends but they no longer do that.
Cons
There is no professional development. I have had to explain basic mathematical concepts to everyone that is above me. Very much dedicated to 80's corporate culture. Sending e-mails in the chain of command is the norm/enforced, e.g. if sally on team A wants to ask for something from Joey on Team B she has to send an e-mail to her boss who sends it to their director who sends it to another director who sends it to Joey's boss who then sends it to Joey. There is version proliferation for software on company computers. Many people's jobs only exist due to them hoarding information from others, they aren't actually capable of producing any quality work. Multiple managers use fear-based management tactics to get employees to do things. You will at some point be asked to do something that is unethical, tell them NO they will try to pressure you but if you stand firm they will back down. In addition to all this, the company is not growing so there is no room for career growth.
