Applied online and also submitted resume through a job fair. At the fair, I was asked to write a simple program along with simple questions like past projects, interests and experience. I was called for on-site interview event that consisted of approximately 30 recent graduate students. The on-site interview consisted of 4 1:1 interviews. The interview covered OOP concepts, algorithmic and data structure questions about graphs, linked lists, etc. The difficulty level was quite high, though I felt I knew some variation of the questions asked. There were no terrible surprises. Two of the four interviewers were not even interested in my name. They walked in and started asking me questions directly. I asked my last interviewer about "Amazon" culture, he was hesitant to directly answer it. I don't know why he did that. He started telling me the company principles and goals. It was good experience for me and they paid for the tickets and stay at Seattle, So, I was happy with the overall process.
