    Average Interview


    I applied online. The process took 4+ weeks. I interviewed at Marsh & McLennan Companies.


    Phone interview, then in-person. At the time of the in-person they asked if I'd be available to come back and interview with some other people, I replied yes. Left and never heard from anyone ever again. Followed up twice. Terrible when you are interviewing with HR for a job in HR
