The process was in three steps. A pre interview which was short and quick and friendly. The second step was a marketing campaign to pitch back to some of the senior marketing team. They did say there is no right or wrong with what you're presenting, they are looking for strategy. The third is with a final interview with the founders. However, in my case, they joined the pitch, so I have step 2 and 3 in the same meeting which was good.
It was really fun to pitch back, everyone was discussing and we were all sharing ideas and bringing my thoughts to life.
