First a recruiter contacted me via phone and email and asked for some basic information. She explained their hiring standard is looking for good generalist, so I'll be interviewing with several engineers from different teams. Then she arranged one round of phone screening with a person, who asked about my resume questions and some simple programming and design questions. Then next stay she contacted me for arranging an onsite. The onsite was with 6 engineers, from 3 year googler to googler from start-up, including a very senior engineer/researcher. They are all very kind and interview is quick-paced. On average each asked 3-5 questions covering algorithm, coding, knowledge, experience, design, and my research. They passed on a piece of paper to avoid asking same questions.
