Applied online and was contacted within a couple of days to arrange a telephone interview. This was easy to arrange and was then conducted through Amazons Chime service - had no issues operating it. The telephone interview was with the hiring manager and lasted around 45 minutes. The questions were based entirely around Amazons leadership principles. I was then contacted a couple of hours later to invite me in for a face to face interview at the London office. This was 4 interviews lasting around an hour each. Three interviewers were directly related to the role and one was a bar raiser - google it. They again were completely about the leadership principles. The best advice I can give you is learn them inside out and back to front. There’s loads of YouTube content out there to help you prepare for commonly asked questions - this helped me so much!
