I went through a recruitment company and got fast tracked to the first interview. Involved questions such as explain the most difficult aspect of working in a team and why, specifically, do you want to work for Detica? Then I had some maths questions involving estimating the amount of water flowing past me in any 24 hour period when standing at the edge of the Thames in central london. I think they just wanted to see how logical my thinking was. Then I had a basic programming question which was not particularly easy but it went okay. I passed that interview and now have a second round interview next week.
