First was phone interview. It lasted about 30minutes. I've got only technical questions. After the interview I could ask some questions about comapny and position. Next I have got feedback. It was positive so I was invited for a face to face interview. Face to face interview was in London, with two team members. I've got to describe my current project, response to some technical questions, write on a board some simple algorithm and try to find solutions to problems they have to solve normaly.
