I was met at front desk by coordinator, and then showed around the office (was offered water, tea, coffee). I then had four half-hour interviews with different engineers. The first interview covered some systems knowledge questions, a web page design, and a simpler coding question. The second interview involved another coding question on the simpler side, and discussion about the type of project that I would like to work on. The third and fourth interviews, were a single coding question of above average difficulty.
