Pros
Treat people well - flexible hours, good compensation and benefits, ability to work from home, and managers that respect work life balance. You get a 3 month sabbattical after 10 yrs working. Great at what they do - and lots of opportunity to do interesting work. Very accessible senior management and executive team. Feels like a small company though its roughly 1500-people strong. Not too hard to navigate. People are genuinely friendly and there are some deeply talented individuals here.
Cons
Traditionally an underwriting-led company, so other functions have to shout to be heard. Slow to change when it comes to technology and the core business. Many people have worked here for 10+ years. Smaller company means its harder to move around departments as jobs don't come up that often. A little bit of unconscious bias does exist in pockets in management.
