I'm still in the process (need to submit the report mentioned below) and will be updating this. I did a telephonic interview that lasted about 20 minutes, after which I was given a case study to report on. The interviewer was very professional and easy to chat to. It was a bit more casual than I'd expected but that made me feel more comfortable.

Very thorough and intense. Not only do they ask questions to assess our knowledge of digital marketing, they look to find out about who you are as a person. Culture is such a big thing there and there is a big family vibe and so there is a very comprehensive approach to interviewing. Expect a lot of questions that will require out of the box thinking and somewhat unorthodox responses. Before I was hired I had to write in a case study response and then did a Skype interview with the HR/Talent Officer there after which I had a first interview with key staff and then final interview with the MD and GM. It is a very fun process and they appreciate it if you read up on the content they publish to their blog and watch all the fun stuff they post on YouTube.
