They have asked me questions related to my problem-solving skills, strategy and tools that I have used. Communication style, flexibility and energy were also general concerns of the recruiters. In more detail: the problem-solving skills, I was asked how I would handle different situations that are likely to happen. Strategy and tools were asked so they could have an impression on my work routine and self-management. Communication, flexibility and energy were asked so they could get a glimpse of how easy I was to work with, as a team member. Some of the questions were tricky, and I think people with a bit less experience on the field might have a harder time finding an answer.
