It's a pretty long process time wise. First was coding round, on Codility.com; stupid easy question. Second was video interview; this was not live, but rather one where you must record your response to 5 questions and submit. Third was in-person interview; straightforward and easy. The whole process on average takes around 2-3 months. For the video interview, you usually get the list of 5 questions in advance and then by a fixed date you must log-in and record you responses. You only have 5 minutes to answer each question. The coding part is rather stupid, but I have heard they have since improved the system; they used to ask the same coding question for 3 years in a row. You only have one hour to live code and submit the solution, I think you have a choice of C/C++ and Java, the question is not informed to you beforehand.
