I applied online; 3 weeks later I was asked to take an online assessment: verbal & numerical reasoning, plus a personality quiz. 5-6 weeks later I received an opportunity to interview in a month's time at their UK HQ. The interview was with the head of HR plus a technical manager; and consisted of standard situational questions over 30-40 mins. The results of my online assessment were then presented to me. I was informed of their decision a week later.
