The process took about two weeks and included three stages.
The first stage was a 15-20 minute phone call with the team leader, getting to know each other and what I was looking for.
The second stage was a professional interview in the offices, they presented all kinds of data and graphs and asked me to tell them what my insights were. In addition, I had to perform operations in Excel on campaign data.
The final stage was another one-hour interview with the director.
