The interview lasts for approximately 3-4 rounds, with one of them serving as a means to go over the answers you have recorded for a mini-assignment they give you. In comparison to other companies, I found the assignment to not only be in-depth to prove whether you have a good understanding of the brand identity, but it did keep in mind that you most probably are applying to other companies throughout your studies as well, cutting it down to a manageable format.
I felt very relaxed and comfortable throughout the interviews with both of my to-be supervisors, although one of them has since left the company. I therefore can't speak for the new worker who may have taken over her role and what they are like; but with everyone being relatively polite and cordial, I would not be surprised if they had a similar open demeanor. I would recommend, but only if looking for a short-term internship.
