Very efficient process. They went through resume one by one and always interest in the story behind the projects. After the phone interview, on-site is more tough. Most about C++ and probabilities

Directly gave me some questions about statistic and probability, also some brain teasers. Although I only wrote "experienced" in C++, he still asked me some C++ questions. The interviewer was really calm, giving me a feeling that he was going through a list of questions.
