Don´t expect questions, expect to conduct a one on one conversation about your real life experience, you will be asked to tell different experiences in your professional life related with some specific subjects, these will vary from one interview to other, but the fact is you are asked to show your experiences and have the skill to tell them clearly. Know you thing is my advice. Be prepared to give a presentation to a panel of experts, and conduct one on one interviews with several key members of the team and building a real life solution on the whiteboard for problems very big in scale. There is no limit on how big the problem is, so you will have to use all the experience you have. Just give the interview is like doing and MBA style of preparation, i prepare myself for 3 months. These is the level inside Amazon senior SA´s don´t think it´s easy Amazon is willing to get the best talent worldwide and the best fit for the job. These means if you are not the best choice for a position, may be you mistake selecting it. I feel these whole process make me become better than before, i´m happy with the experience.
