The interview process was fair. You had your choice of three different departments. If any of the departments saw a fit, they would have two managers reach out and conduct an interview; if you made it past that, another higher up manager will interview you, and a final decision will be made.
In my case, I had interviews with two different departments, Digital Media and Marketing. I had three phone interviews with marketing, and one for digital media. I had accepted an offer for marketing once it was given, and I alerted the digital media department.
