    Average Interview


    I applied through an employee referral. The process took a week. I interviewed at Marsh & McLennan Companies (Witham, England) in November 2019.


    Everyone was friendly and welcoming and made me feel at ease. It was a very quick process and I was contacted for a 2nd interview within days. I was called with an offer just after my 2nd interview and I accepted. Looking forward to starting with Marsh in January.
