Was contacted by the recruitment team after placing my CV on a third-party recruitment website and was invited to an assessment day within a week. Due to the time of year (exam period) I was in a small group, although on average groups are usually around 15 people. We sat a short technical test, and a competency test which were used to judge our relative abilities. We were asked as a group to research a piece of technology and create a presentation that we would present to the interview organisers. After this we went for a one on one interview with someone from the company, which was relaxed and nor pressurised. I heard back within a week.
