after two rounds of phone interview, took a plane to SF, EA maxis headquarter for an onsite interview. There were three rounds, first round was two young engineer asking some resumes questions and then some geometry question solving. After that, recuriter took me a tour around office a little bit before I entered the second round facing two senior engineers. Questions are kinda simple, basically about OO language in C# and some C++ tricks. Last is a leisure interview with the project manager, nothing needs to be noticed.
