Okay, the structure could be explained earlier to get a better understanding of what is expected. Given the task and asked to describe it, they are expecting a presentation style or maybe ask questions around the answer given; clarity could be a lot better.

The interview process was explained properly by the hiring manager. They told me that I would have a phone call as a first stage and should I be successful, be invited to a second and final interview involving a presentation from my side and a nice Q&A chat with the managers. The brief for the presentation provided all the information needed to create an engaging and informative presentation. The questions were straightforward - ambition regarding the position and company, competitor knowledge, industry knowledge etc. I would say the whole process was very recommendable and pleasant, with everyone being incredibly nice and welcoming and overall had a great experience.
