It was a group interview. There were 3 or 2 people in each group. Each group has a project to do. 3 tasks in a project. You have to discuss with your teammates and assign every member a task to do. When you were doing the project, there were 2 interviews. In each interview, you have to talk with 2 people, and show you progress and result. You can use C++, Java, and Python to do the project. Java has eclipse, and C++ has VS. I chose Java.
