It's usually an interview with the team leader followed by another interview with his manager in a week or two. Some interviews are one on one while some others involve 2 interviewers in the room as well as another one on the video conference. It all depends on which position and team you're applying for. Don't worry about technical questions since it won't be too hard. One of the first interviewers will be your manager and don't forget to shave and suit up.
