I had two interviews at GroupM. The first was with my now line manager, which was more of a question and answer session since I was new to the world of media. He was very patient and understanding and talked me through the role in a way I could understand it. I was invited back for a second stage where two of the Senior Optimisation managers asked me more detailed questions about programmatic and media and why I would like to work at GroupM. I was given an answer the next day by the talent team at GroupM, and beforehand had been given excellent support and interview coaching
