A mixed bag ... but a diverse worldwide company that offers many opportunities to advance in, or change, your career. - Avis employé Actuarial Analyst Mercer

Mercer is a very large publicly traded company, and consequently the bottom line (revenues) are the constant driving factor. Some managers are less equipped to manage people while faced with the pressures to improve the bottom line, and consequently the employee may get "thrown under the bus". Ask about things like employee turnover before accepting an offer here. And be aware that although some offices are managed pretty badly and feel like a war zone, others are managed really well and feel like a community. There are a lot of opportunities to change, if your current position doesn't make you happy!
