Pros
The people are very friendly and supportive and there is a good work / life balance. Pay is fair but not the highest in the industry, although the benefits are very good. The P&I industry has a relatively flat structure so some new joiners can become frustrated by the pace of career progression. If you accept that the world of P&I moves slowly, there is certainly scope to gain seniority and increase your salary. Many people in the company that have been there 10, 20, 30 or 40(!) years, so there are plenty of people to learn from. I recommend buying shares as soon as possible. You are only allowed to purchase up to 1% of your salary per year, but the high dividends means they pay for themselves in a couple of years.
Cons
The claims hierarchy is fairly flat, you need to be patient to make significant advancement. There is often resistance to adopting new ideas.
