Leadership principles : Amazon does focus quite a lot on them and your recruiter can help you prepare. Each 45 minute interview will typically consist of 20 minutes of leadership principles questions and the remaining 25 minutes are reserved for one coding/design question. Use the S.T.A.R. pattern and you should be fine.
