    I worked at Marsh & McLennan Companies full-time (More than 3 years)


    The Marsh brand is a big name in insurance and carries a lot of weight with clients, carriers, and others in the industry. There are lots of resources available to you if you know where to find them. You will have access to many talented and experienced colleagues.


    Change comes slowly in a large organization like this. There is little thought given to the size or makeup of the book assigned to you. Work/life balance issues. Management ranges from excellent to incompetent (and everything in between).

    Advice to Management

    Your greatest assets are the Marsh name and your employees.

    Average Interview


    I applied online. I interviewed at Marsh & McLennan Companies (Hoboken, NJ).


    Applied online through LinkedIn, the entire interview process took about two months. I had two interview sessions in total, a video interview with HireVue and an in-person interview with the Audit Management Team at the New Jersey Office.

    The in-person interview was a great experience, I met with Senior Manager and Directors from the Department and they were very knowledgeable and passionate about Company. During the interview, they provided a great overview of the day-to-day operations within the Department.

    I was notified with an offer a day after in-person interview and have accepted the offer.
