Was sent a coding test with a question whereafter I was invited to come down to the London Development center for a on-site interview. The interview started directly with a whiteboard coding question involving a game (whose name I've forgotten sorry), after that there was a bit time for standard competency questions. It took one hour in total. Afterwards we were given a tour of the office. There was two interviewers who both had their nose down their laptop for the majority of the interview typing away notes (i presume) which was a bit of a distraction.
