The interview was during an Assessment day. Lasted 30 minutes. The Interviewer had preset questions and only asked them. Other tasks during the day included a scheduling task where you have to arrange a meeting while looking at attendees calendars, a task where you compare bits of data and a task where you read a book on how to fly a plane and then have to teach an assessor how to fly a plane. This final task was difficult and wasn't helped by being explained poorly.
