Two 45 min phone interviews and half a day at Slough, four one hour interviews of which three were from people in a similar more senior role and one from a totally different part of Amazon. Also completed an online maths test, can't see the point of doing this at home, it should have been done in the office in my opinion as it could quite easily have been completed by someone else. All questions were competency based STAR analogy which I thought got a good idea of my thought process and brought up several different business experiences. However in addition it would have made sense to directly ask me about my previous role and how I thought that qualified me for this, what would I change once in the new role etc.
