Pros
AIG is still a major force in the insurance market. Its sheer size and success as an insurance company mean it is less likely to fail in the long term no matter how bad things get in the short term. AIG offers multiple opportunities across multiple disciplines and is finally learning to operate horizontally in a vertical environment - That alone will bring rewards in the mid to long term. finally, AIG is a company where the majority off people actuall care - you may be a number, but you are a number that matters even in more trying times.
Kontras
changing goalposts, prevalence (still) of yes men rather than managers, inconsistent systems, procedures and processes across groups. AIG is a company still living in the past where acquisitions are left alone as long as they make money and the phenominal growth of the company has not been mirrored in a growth in shared, consistent services or infrastructure. AIG is also slow to offer benefits that are meaningful - pension and healthcare are not in the same league as similar companies. Lastly performance review is so hit and miss that its laughable - if you want to know how you are doing its impossible to find out.
