I applied online and got a phone call the day before the group interview. They asked me some brief questions over the phone like why do you want to work at Zara etc. In the interview we filled out an availability form. We also had 2 minutes to get to know the person next to us and then introduce them to the rest of the group. We were also split into 2 groups and performed a scenario. Then we got given little cards with 1 question each on them (and we weren't allowed to look at the question until it was our turn). We had to read the question out loud and answer it in front of everyone.
