    Systems Administrator Interview

    Anonymous Employee in United States
    No Offer
    Neutral Experience
    Average Interview

    I applied online. I interviewed at Marsh McLennan (United States)


    Went through 3 different interviews only to be ghosted and to get no response of follow ups. This included the initial phone screen, interview with the hiring manager and team, and 3rd interview with the regional manager. Very unprofessional to not at least reach out and state that I did not get the position.

    Basic Sys Admin interview questions.
