I was placed on assignment at Marsh through a local temp agency. Waited a year, as supervisor made the case to develop a permanent position for me. When the time came, Marsh made an offer and its sister company Mercer also offered me a position in another office. This was nice as I had them both trying to outbid the other. The interview process was very straightforward only because I had worked with both companies (Mercer more sporadically, by way of Marsh) for over a year and had thus proven my worth.
